+
+<p>
+Building Apache Tomcat from source is very easy, and is the first step to
+contributing to Tomcat. The complete and comprehensive instructions are
+provided in the file <a href="BUILDING.txt">BUILDING.txt</a>.
+The following is a quick step by step guide.
+</p>
+
+</div><h3 id="Download_a_Java_Development_Kit_(JDK)_version_8">Download a Java Development Kit (JDK) version 8</h3><div class="text">
+
+<p>
+Building Apache Tomcat requires a JDK (version 8) to be installed. You can download one from<br>
+<a href="http://www.oracle.com/technetwork/java/javase/downloads/index.html">http://www.oracle.com/technetwork/java/javase/downloads/index.html</a><br>
+<a href="http://openjdk.java.net/install/index.html">http://openjdk.java.net/install/index.html</a><br>
+or another JDK vendor.
+</p>
+
+<p>
+<b>IMPORTANT</b>: Set an environment variable JAVA_HOME to the pathname of the
+directory into which you installed the JDK release.
+</p>
+
+</div><h3 id="Install_Apache_Ant_1.9.8_or_later">Install Apache Ant 1.9.8 or later</h3><div class="text">
+
+<p>
+Download a binary distribution of Ant 1.9.8 or later from
+<a href="https://ant.apache.org/bindownload.cgi">here</a>.
+</p>
+
+<p>
+Unpack the binary distribution into a convenient location so that the
+Ant release resides in its own directory (conventionally named
+<code>apache-ant-1.9.x</code>). For the remainder of this guide,
+the symbolic name <code>${ant.home}</code> is used to refer to the full pathname of
+ the Ant installation directory.
+</p>
+
+<p>
+<b>IMPORTANT</b>: Create an ANT_HOME environment variable to point the directory <code>${ant.home}</code>,
+and modify the PATH environment variable to include directory
+<code>${ant.home}/bin</code> in its list. This makes the <code>ant</code> command line script
+available, which will be used to actually perform the build.
+</p>
+
+</div><h3 id="Checkout_or_obtain_the_Tomcat_source_code">Checkout or obtain the Tomcat source code</h3><div class="text">
+
+ <p>
+ Tomcat SVN repository URL:
+ <a href="https://svn.apache.org/repos/asf/tomcat/trunk/">https://svn.apache.org/repos/asf/tomcat/trunk/</a>
+ </p>
+ <p>
+ Tomcat source packages:
+ <a href="https://tomcat.apache.org/download-90.cgi">https://tomcat.apache.org/download-90.cgi</a>.
+ </p>
+
+ <p>
+ Checkout the source using SVN, selecting a tag for released version or
+ trunk for the current development code, or download and unpack a
+ source package. For the remainder of this guide, the symbolic name
+ <code>${tomcat.source}</code> is used to refer to the
+ location where the source has been placed.
+ </p>
+
+</div><h3 id="Configure_download_area">Configure download area</h3><div class="text">
+
+<p>
+ Building Tomcat involves downloading a number of libraries that it depends on.
+ It is strongly recommended to configure download area for those libraries.
+</p>
+
+<p>
+ By default the build is configured to download the dependencies into the
+ <code>${user.home}/tomcat-build-libs</code> directory. You can change this
+ (see below) but it must be an absolute path.
+</p>
+
+<p>
+ The build is controlled by creating a
+ <code>${tomcat.source}/build.properties</code> file. It can be used to
+ redefine any property that is present in <code>build.properties.default</code>
+ and <code>build.xml</code> files. The <code>build.properties</code> file
+ does not exist by default. You have to create it.
+</p>
+
+<p>
+ The download area is defined by property <code>base.path</code>. For example:
+</p>
+
+<div class="codeBox"><pre><code># ----- Default Base Path for Dependent Packages -----
+# Replace this path with the directory path where
+# dependencies binaries should be downloaded.
+base.path=/home/me/some-place-to-download-to</code></pre></div>
+
+<p>
+ Different versions of Tomcat are allowed to share the same download area.
+</p>
+
+<p>
+ Another example:
+</p>
+
+<div class="codeBox"><pre><code>base.path=${user.dir}/../libraries-tomcat9.0</code></pre></div>
+
+<p>
+ Users who access the Internet through a proxy must use the properties
+ file to indicate to Ant the proxy configuration:
+</p>
+
+<div class="codeBox"><pre><code># ----- Proxy setup -----
+proxy.host=proxy.domain
+proxy.port=8080
+proxy.use=on</code></pre></div>
+
+</div><h3 id="Building_Tomcat">Building Tomcat</h3><div class="text">
+
+<p>
+Use the following commands to build Tomcat:
+</p>
+
+<p>
+<code>cd ${tomcat.source}</code><br>
+<code>ant</code>
+</p>
+
+<p>
+Once the build has completed successfully, a usable Tomcat installation will have been
+produced in the <code>${tomcat.source}/output/build</code> directory, and can be started
+and stopped with the usual scripts.
+</p>
+</div><h3 id="Building_with_Eclipse">Building with Eclipse</h3><div class="text">
+
+<p>
+<b>IMPORTANT:</b> This is not a supported means of building Tomcat; this information is
+provided without warranty :-).
+The only supported means of building Tomcat is with the Ant build described above.
+However, some developers like to work on Java code with a Java IDE,
+and the following steps have been used by some developers.
+</p>
+
+<p>
+<b>NOTE:</b> This will not let you build everything under Eclipse;
+the build process requires use of Ant for the many stages that aren't
+simple Java compilations.
+However, it will allow you to view and edit the Java code,
+get warnings, reformat code, perform refactorings, run Tomcat
+under the IDE, and so on.
+</p>
+
+<p>
+<b>WARNING:</b> Do not forget to create and configure
+ <code>${tomcat.source}/build.properties</code> file as described above
+ before running any Ant targets.
+</p>
+
+<p>
+Sample Eclipse project files and launch targets are provided in the
+<code>res/ide-support/eclipse</code> directory of the source tree.
+The instructions below will automatically copy these into the required locations.
+</p>
+<p>
+An Ant target is provided as a convenience to download all binary dependencies, and to create
+the Eclipse project and classpath files in the root of the source tree.
+</p>
+
+<p>
+<code>cd ${tomcat.source}</code><br>
+<code>ant ide-eclipse</code>
+</p>
+
+<p>
+Start Eclipse and create a new Workspace.
+</p>
+
+<p>
+Open the <em>Preferences</em> dialog and then select <em>Java->Build Path->Classpath
+Variables</em> to add two new <em>Classpath Variables</em>:
+</p>
+
+
+<table class="defaultTable">
+ <tr><td>TOMCAT_LIBS_BASE</td><td>The same location as the <code>base.path</code>
+ setting in <code>build.properties</code>, where the binary dependencies have been downloaded</td></tr>
+ <tr><td>ANT_HOME</td><td>the base path of Ant 1.9.8 or later</td></tr>
+</table>
+
+
+<p>
+Use <em>File->Import</em> and choose <em>Existing Projects into Workspace</em>.
+From there choose the root directory of the Tomcat source tree (<code>${tomcat.source}</code>)
+and import the Tomcat project located there.
+</p>
+
+<p>
+<code>start-tomcat</code> and <code>stop-tomcat</code> launch configurations are provided in
+<code>res/ide-support/eclipse</code> and will be available in the <em>Run->Run Configurations</em>
+dialog. Use these to start and stop Tomcat from Eclipse.
+If you want to configure these yourself (or are using a different IDE)
+then use <code>org.apache.catalina.startup.Bootstrap</code> as the main class,
+<code>start</code>/<code>stop</code> etc. as program arguments, and specify <code>-Dcatalina.home=...</code>
+(with the name of your build directory) as VM arguments.
+</p>
+
+<p>
+Tweaking a few formatting preferences will make it much easier to keep consistent with Tomcat
+coding conventions (and have your contributions accepted):
+</p>
+
+<table class="defaultTable">
+ <tr><td>Java -> Code Style -> Formatter -> Edit...</td>
+ <td>Tab policy: Spaces only<br>Tab and Indentation size: 4</td></tr>
+ <tr><td>General -> Editors -> Text Editors</td>
+ <td>Displayed tab width: 2<br>Insert spaces for tabs<br>Show whitespace characters (optional)</td></tr>
+ <tr><td>XML -> XML Files -> Editor</td><td>Indent using spaces<br>Indentation size: 2</td></tr>
+ <tr><td>Ant -> Editor -> Formatter</td><td>Tab size: 2<br>Use tab character instead of spaces: unchecked</td></tr>
+</table>
+
+<p>
+The recommended configuration of Compiler Warnings is documented in
+<code>res/ide-support/eclipse/java-compiler-errors-warnings.txt</code> file.
+</p>
+
+</div><h3 id="Building_with_other_IDEs">Building with other IDEs</h3><div class="text">
+<p>
+The same general approach should work for most IDEs; it has been reported
+to work in IntelliJ IDEA, for example.

+
+<p>
+Building Apache Tomcat from source is very easy, and is the first step to
+contributing to Tomcat. The complete and comprehensive instructions are
+provided in the file <a href="BUILDING.txt">BUILDING.txt</a>.
+The following is a quick step by step guide.
+</p>
+
+</div><h3 id="Download_a_Java_Development_Kit_(JDK)_version_8">Download a Java Development Kit (JDK) version 8</h3><div class="text">
+
+<p>
+Building Apache Tomcat requires a JDK (version 8) to be installed. You can download one from<br>
+<a href="http://www.oracle.com/technetwork/java/javase/downloads/index.html">http://www.oracle.com/technetwork/java/javase/downloads/index.html</a><br>
+<a href="http://openjdk.java.net/install/index.html">http://openjdk.java.net/install/index.html</a><br>
+or another JDK vendor.
+</p>
+
+<p>
+<b>IMPORTANT</b>: Set an environment variable JAVA_HOME to the pathname of the
+directory into which you installed the JDK release.
+</p>
+
+</div><h3 id="Install_Apache_Ant_1.9.8_or_later">Install Apache Ant 1.9.8 or later</h3><div class="text">
+
+<p>
+Download a binary distribution of Ant 1.9.8 or later from
+<a href="https://ant.apache.org/bindownload.cgi">here</a>.
+</p>
+
+<p>
+Unpack the binary distribution into a convenient location so that the
+Ant release resides in its own directory (conventionally named
+<code>apache-ant-1.9.x</code>). For the remainder of this guide,
+the symbolic name <code>${ant.home}</code> is used to refer to the full pathname of
+ the Ant installation directory.
+</p>
+
+<p>
+<b>IMPORTANT</b>: Create an ANT_HOME environment variable to point the directory <code>${ant.home}</code>,
+and modify the PATH environment variable to include directory
+<code>${ant.home}/bin</code> in its list. This makes the <code>ant</code> command line script
+available, which will be used to actually perform the build.
+</p>
+
+</div><h3 id="Checkout_or_obtain_the_Tomcat_source_code">Checkout or obtain the Tomcat source code</h3><div class="text">
+
+ <p>
+ Tomcat SVN repository URL:
+ <a href="https://svn.apache.org/repos/asf/tomcat/trunk/">https://svn.apache.org/repos/asf/tomcat/trunk/</a>
+ </p>
+ <p>
+ Tomcat source packages:
+ <a href="https://tomcat.apache.org/download-90.cgi">https://tomcat.apache.org/download-90.cgi</a>.
+ </p>
+
+ <p>
+ Checkout the source using SVN, selecting a tag for released version or
+ trunk for the current development code, or download and unpack a
+ source package. For the remainder of this guide, the symbolic name
+ <code>${tomcat.source}</code> is used to refer to the
+ location where the source has been placed.
+ </p>
+
+</div><h3 id="Configure_download_area">Configure download area</h3><div class="text">
+
+<p>
+ Building Tomcat involves downloading a number of libraries that it depends on.
+ It is strongly recommended to configure download area for those libraries.
+</p>
+
+<p>
+ By default the build is configured to download the dependencies into the
+ <code>${user.home}/tomcat-build-libs</code> directory. You can change this
+ (see below) but it must be an absolute path.
+</p>
+
+<p>
+ The build is controlled by creating a
+ <code>${tomcat.source}/build.properties</code> file. It can be used to
+ redefine any property that is present in <code>build.properties.default</code>
+ and <code>build.xml</code> files. The <code>build.properties</code> file
+ does not exist by default. You have to create it.
+</p>
+
+<p>
+ The download area is defined by property <code>base.path</code>. For example:
+</p>
+
+<div class="codeBox"><pre><code># ----- Default Base Path for Dependent Packages -----
+# Replace this path with the directory path where
+# dependencies binaries should be downloaded.
+base.path=/home/me/some-place-to-download-to</code></pre></div>
+
+<p>
+ Different versions of Tomcat are allowed to share the same download area.
+</p>
+
+<p>
+ Another example:
+</p>
+
+<div class="codeBox"><pre><code>base.path=${user.dir}/../libraries-tomcat9.0</code></pre></div>
+
+<p>
+ Users who access the Internet through a proxy must use the properties
+ file to indicate to Ant the proxy configuration:
+</p>
+
+<div class="codeBox"><pre><code># ----- Proxy setup -----
+proxy.host=proxy.domain
+proxy.port=8080
+proxy.use=on</code></pre></div>
+
+</div><h3 id="Building_Tomcat">Building Tomcat</h3><div class="text">
+
+<p>
+Use the following commands to build Tomcat:
+</p>
+
+<p>
+<code>cd ${tomcat.source}</code><br>
+<code>ant</code>
+</p>
+
+<p>
+Once the build has completed successfully, a usable Tomcat installation will have been
+produced in the <code>${tomcat.source}/output/build</code> directory, and can be started
+and stopped with the usual scripts.

+<b>IMPORTANT:</b> This is not a supported means of building Tomcat; this information is
+provided without warranty :-).
+The only supported means of building Tomcat is with the Ant build described above.
+However, some developers like to work on Java code with a Java IDE,
+and the following steps have been used by some developers.
+</p>
+
+<p>
+<b>NOTE:</b> This will not let you build everything under Eclipse;
+the build process requires use of Ant for the many stages that aren't
+simple Java compilations.
+However, it will allow you to view and edit the Java code,
+get warnings, reformat code, perform refactorings, run Tomcat
+under the IDE, and so on.
+</p>
+
+<p>
+<b>WARNING:</b> Do not forget to create and configure
+ <code>${tomcat.source}/build.properties</code> file as described above
+ before running any Ant targets.
+</p>
+
+<p>
+Sample Eclipse project files and launch targets are provided in the
+<code>res/ide-support/eclipse</code> directory of the source tree.
+The instructions below will automatically copy these into the required locations.
+</p>
+<p>
+An Ant target is provided as a convenience to download all binary dependencies, and to create
+the Eclipse project and classpath files in the root of the source tree.
+</p>
+
+<p>
+<code>cd ${tomcat.source}</code><br>
+<code>ant ide-eclipse</code>
+</p>
+
+<p>
+Start Eclipse and create a new Workspace.
+</p>
+
+<p>
+Open the <em>Preferences</em> dialog and then select <em>Java->Build Path->Classpath
+Variables</em> to add two new <em>Classpath Variables</em>:
+</p>
+
+
+<table class="defaultTable">
+ <tr><td>TOMCAT_LIBS_BASE</td><td>The same location as the <code>base.path</code>
+ setting in <code>build.properties</code>, where the binary dependencies have been downloaded</td></tr>
+ <tr><td>ANT_HOME</td><td>the base path of Ant 1.9.8 or later</td></tr>
+</table>
+
+
+<p>
+Use <em>File->Import</em> and choose <em>Existing Projects into Workspace</em>.
+From there choose the root directory of the Tomcat source tree (<code>${tomcat.source}</code>)
+and import the Tomcat project located there.
+</p>
+
+<p>
+<code>start-tomcat</code> and <code>stop-tomcat</code> launch configurations are provided in
+<code>res/ide-support/eclipse</code> and will be available in the <em>Run->Run Configurations</em>
+dialog. Use these to start and stop Tomcat from Eclipse.
+If you want to configure these yourself (or are using a different IDE)
+then use <code>org.apache.catalina.startup.Bootstrap</code> as the main class,
+<code>start</code>/<code>stop</code> etc. as program arguments, and specify <code>-Dcatalina.home=...</code>
+(with the name of your build directory) as VM arguments.
+</p>
+
+<p>
+Tweaking a few formatting preferences will make it much easier to keep consistent with Tomcat
+coding conventions (and have your contributions accepted):
+</p>
+
+<table class="defaultTable">
+ <tr><td>Java -> Code Style -> Formatter -> Edit...</td>
+ <td>Tab policy: Spaces only<br>Tab and Indentation size: 4</td></tr>
+ <tr><td>General -> Editors -> Text Editors</td>
+ <td>Displayed tab width: 2<br>Insert spaces for tabs<br>Show whitespace characters (optional)</td></tr>
+ <tr><td>XML -> XML Files -> Editor</td><td>Indent using spaces<br>Indentation size: 2</td></tr>
+ <tr><td>Ant -> Editor -> Formatter</td><td>Tab size: 2<br>Use tab character instead of spaces: unchecked</td></tr>
+</table>
+
+<p>
+The recommended configuration of Compiler Warnings is documented in
+<code>res/ide-support/eclipse/java-compiler-errors-warnings.txt</code> file.

+<p>
+Building Apache Tomcat from source is very easy, and is the first step to
+contributing to Tomcat. The complete and comprehensive instructions are
+provided in the file <a href="BUILDING.txt">BUILDING.txt</a>.
+The following is a quick step by step guide.
+</p>
+
+</div><h3 id="Download_a_Java_Development_Kit_(JDK)_version_8">Download a Java Development Kit (JDK) version 8</h3><div class="text">
+
+<p>
+Building Apache Tomcat requires a JDK (version 8) to be installed. You can download one from<br>
+<a href="http://www.oracle.com/technetwork/java/javase/downloads/index.html">http://www.oracle.com/technetwork/java/javase/downloads/index.html</a><br>
+<a href="http://openjdk.java.net/install/index.html">http://openjdk.java.net/install/index.html</a><br>
+or another JDK vendor.
+</p>
+
+<p>
+<b>IMPORTANT</b>: Set an environment variable JAVA_HOME to the pathname of the
+directory into which you installed the JDK release.
+</p>
+
+</div><h3 id="Install_Apache_Ant_1.9.8_or_later">Install Apache Ant 1.9.8 or later</h3><div class="text">
+
+<p>
+Download a binary distribution of Ant 1.9.8 or later from
+<a href="https://ant.apache.org/bindownload.cgi">here</a>.
+</p>
+
+<p>
+Unpack the binary distribution into a convenient location so that the
+Ant release resides in its own directory (conventionally named
+<code>apache-ant-1.9.x</code>). For the remainder of this guide,
+the symbolic name <code>${ant.home}</code> is used to refer to the full pathname of
+ the Ant installation directory.
+</p>
+
+<p>
+<b>IMPORTANT</b>: Create an ANT_HOME environment variable to point the directory <code>${ant.home}</code>,
+and modify the PATH environment variable to include directory
+<code>${ant.home}/bin</code> in its list. This makes the <code>ant</code> command line script
+available, which will be used to actually perform the build.
+</p>
+
+</div><h3 id="Checkout_or_obtain_the_Tomcat_source_code">Checkout or obtain the Tomcat source code</h3><div class="text">
+
+ <p>
+ Tomcat SVN repository URL:
+ <a href="https://svn.apache.org/repos/asf/tomcat/trunk/">https://svn.apache.org/repos/asf/tomcat/trunk/</a>
+ </p>
+ <p>
+ Tomcat source packages:
+ <a href="https://tomcat.apache.org/download-90.cgi">https://tomcat.apache.org/download-90.cgi</a>.
+ </p>
+
+ <p>
+ Checkout the source using SVN, selecting a tag for released version or
+ trunk for the current development code, or download and unpack a
+ source package. For the remainder of this guide, the symbolic name
+ <code>${tomcat.source}</code> is used to refer to the
+ location where the source has been placed.
+ </p>
+
+</div><h3 id="Configure_download_area">Configure download area</h3><div class="text">
+
+<p>
+ Building Tomcat involves downloading a number of libraries that it depends on.
+ It is strongly recommended to configure download area for those libraries.
+</p>
+
+<p>
+ By default the build is configured to download the dependencies into the
+ <code>${user.home}/tomcat-build-libs</code> directory. You can change this
+ (see below) but it must be an absolute path.
+</p>
+
+<p>
+ The build is controlled by creating a
+ <code>${tomcat.source}/build.properties</code> file. It can be used to
+ redefine any property that is present in <code>build.properties.default</code>
+ and <code>build.xml</code> files. The <code>build.properties</code> file
+ does not exist by default. You have to create it.
+</p>
+
+<p>
+ The download area is defined by property <code>base.path</code>. For example:
+</p>
+
+<div class="codeBox"><pre><code># ----- Default Base Path for Dependent Packages -----
+# Replace this path with the directory path where
+# dependencies binaries should be downloaded.
+base.path=/home/me/some-place-to-download-to</code></pre></div>
+
+<p>
+ Different versions of Tomcat are allowed to share the same download area.
+</p>
+
+<p>
+ Another example:
+</p>
+
+<div class="codeBox"><pre><code>base.path=${user.dir}/../libraries-tomcat9.0</code></pre></div>
+
+<p>
+ Users who access the Internet through a proxy must use the properties
+ file to indicate to Ant the proxy configuration:
+</p>
+
+<div class="codeBox"><pre><code># ----- Proxy setup -----
+proxy.host=proxy.domain
+proxy.port=8080
+proxy.use=on</code></pre></div>
+
+</div><h3 id="Building_Tomcat">Building Tomcat</h3><div class="text">
+
+<p>
+Use the following commands to build Tomcat:
+</p>
+
+<p>
+<code>cd ${tomcat.source}</code><br>
+<code>ant</code>
+</p>
+
+<p>
+Once the build has completed successfully, a usable Tomcat installation will have been
+produced in the <code>${tomcat.source}/output/build</code> directory, and can be started
+and stopped with the usual scripts.
+</p>
+</div><h3 id="Building_with_Eclipse">Building with Eclipse</h3><div class="text">
+
+<p>
+<b>IMPORTANT:</b> This is not a supported means of building Tomcat; this information is
+provided without warranty :-).
+The only supported means of building Tomcat is with the Ant build described above.
+However, some developers like to work on Java code with a Java IDE,
+and the following steps have been used by some developers.
+</p>
+
+<p>
+<b>NOTE:</b> This will not let you build everything under Eclipse;
+the build process requires use of Ant for the many stages that aren't
+simple Java compilations.
+However, it will allow you to view and edit the Java code,
+get warnings, reformat code, perform refactorings, run Tomcat
+under the IDE, and so on.
+</p>
+
+<p>
+<b>WARNING:</b> Do not forget to create and configure
+ <code>${tomcat.source}/build.properties</code> file as described above
+ before running any Ant targets.
+</p>
+
+<p>
+Sample Eclipse project files and launch targets are provided in the
+<code>res/ide-support/eclipse</code> directory of the source tree.
+The instructions below will automatically copy these into the required locations.
+</p>
+<p>
+An Ant target is provided as a convenience to download all binary dependencies, and to create
+the Eclipse project and classpath files in the root of the source tree.
+</p>
+
+<p>
+<code>cd ${tomcat.source}</code><br>
+<code>ant ide-eclipse</code>
+</p>
+
+<p>
+Start Eclipse and create a new Workspace.
+</p>
+
+<p>
+Open the <em>Preferences</em> dialog and then select <em>Java->Build Path->Classpath
+Variables</em> to add two new <em>Classpath Variables</em>:
+</p>
+
+
+<table class="defaultTable">
+ <tr><td>TOMCAT_LIBS_BASE</td><td>The same location as the <code>base.path</code>
+ setting in <code>build.properties</code>, where the binary dependencies have been downloaded</td></tr>
+ <tr><td>ANT_HOME</td><td>the base path of Ant 1.9.8 or later</td></tr>
+</table>
+
+
+<p>
+Use <em>File->Import</em> and choose <em>Existing Projects into Workspace</em>.
+From there choose the root directory of the Tomcat source tree (<code>${tomcat.source}</code>)
+and import the Tomcat project located there.
+</p>
+
+<p>
+<code>start-tomcat</code> and <code>stop-tomcat</code> launch configurations are provided in
+<code>res/ide-support/eclipse</code> and will be available in the <em>Run->Run Configurations</em>
+dialog. Use these to start and stop Tomcat from Eclipse.
+If you want to configure these yourself (or are using a different IDE)
+then use <code>org.apache.catalina.startup.Bootstrap</code> as the main class,
+<code>start</code>/<code>stop</code> etc. as program arguments, and specify <code>-Dcatalina.home=...</code>
+(with the name of your build directory) as VM arguments.
+</p>
+
+<p>
+Tweaking a few formatting preferences will make it much easier to keep consistent with Tomcat
+coding conventions (and have your contributions accepted):
+</p>
+
+<table class="defaultTable">
+ <tr><td>Java -> Code Style -> Formatter -> Edit...</td>
+ <td>Tab policy: Spaces only<br>Tab and Indentation size: 4</td></tr>
+ <tr><td>General -> Editors -> Text Editors</td>
+ <td>Displayed tab width: 2<br>Insert spaces for tabs<br>Show whitespace characters (optional)</td></tr>
+ <tr><td>XML -> XML Files -> Editor</td><td>Indent using spaces<br>Indentation size: 2</td></tr>
+ <tr><td>Ant -> Editor -> Formatter</td><td>Tab size: 2<br>Use tab character instead of spaces: unchecked</td></tr>
+</table>
+
+<p>
+The recommended configuration of Compiler Warnings is documented in
+<code>res/ide-support/eclipse/java-compiler-errors-warnings.txt</code> file.

+Use the following commands to build Tomcat:
+</p>
+
+<p>
+<code>cd ${tomcat.source}</code><br>
+<code>ant</code>
+</p>
+
+<p>
+Once the build has completed successfully, a usable Tomcat installation will have been
+produced in the <code>${tomcat.source}/output/build</code> directory, and can be started
+and stopped with the usual scripts.

+<p>
+<b>IMPORTANT:</b> This is not a supported means of building Tomcat; this information is
+provided without warranty :-).
+The only supported means of building Tomcat is with the Ant build described above.
+However, some developers like to work on Java code with a Java IDE,
+and the following steps have been used by some developers.
+</p>
+
+<p>
+<b>NOTE:</b> This will not let you build everything under Eclipse;
+the build process requires use of Ant for the many stages that aren't
+simple Java compilations.
+However, it will allow you to view and edit the Java code,
+get warnings, reformat code, perform refactorings, run Tomcat
+under the IDE, and so on.
+</p>
+
+<p>
+<b>WARNING:</b> Do not forget to create and configure
+ <code>${tomcat.source}/build.properties</code> file as described above
+ before running any Ant targets.
+</p>
+
+<p>
+Sample Eclipse project files and launch targets are provided in the
+<code>res/ide-support/eclipse</code> directory of the source tree.
+The instructions below will automatically copy these into the required locations.
+</p>
+<p>
+An Ant target is provided as a convenience to download all binary dependencies, and to create
+the Eclipse project and classpath files in the root of the source tree.
+</p>
+
+<p>
+<code>cd ${tomcat.source}</code><br>
+<code>ant ide-eclipse</code>
+</p>
+
+<p>
+Start Eclipse and create a new Workspace.
+</p>
+
+<p>
+Open the <em>Preferences</em> dialog and then select <em>Java->Build Path->Classpath
+Variables</em> to add two new <em>Classpath Variables</em>:
+</p>
+
+
+<table class="defaultTable">
+ <tr><td>TOMCAT_LIBS_BASE</td><td>The same location as the <code>base.path</code>
+ setting in <code>build.properties</code>, where the binary dependencies have been downloaded</td></tr>
+ <tr><td>ANT_HOME</td><td>the base path of Ant 1.9.8 or later</td></tr>
+</table>
+
+
+<p>
+Use <em>File->Import</em> and choose <em>Existing Projects into Workspace</em>.
+From there choose the root directory of the Tomcat source tree (<code>${tomcat.source}</code>)
+and import the Tomcat project located there.
+</p>
+
+<p>
+<code>start-tomcat</code> and <code>stop-tomcat</code> launch configurations are provided in
+<code>res/ide-support/eclipse</code> and will be available in the <em>Run->Run Configurations</em>
+dialog. Use these to start and stop Tomcat from Eclipse.
+If you want to configure these yourself (or are using a different IDE)
+then use <code>org.apache.catalina.startup.Bootstrap</code> as the main class,
+<code>start</code>/<code>stop</code> etc. as program arguments, and specify <code>-Dcatalina.home=...</code>
+(with the name of your build directory) as VM arguments.
+</p>
+
+<p>
+Tweaking a few formatting preferences will make it much easier to keep consistent with Tomcat
+coding conventions (and have your contributions accepted):
+</p>
+
+<table class="defaultTable">
+ <tr><td>Java -> Code Style -> Formatter -> Edit...</td>
+ <td>Tab policy: Spaces only<br>Tab and Indentation size: 4</td></tr>
+ <tr><td>General -> Editors -> Text Editors</td>
+ <td>Displayed tab width: 2<br>Insert spaces for tabs<br>Show whitespace characters (optional)</td></tr>
+ <tr><td>XML -> XML Files -> Editor</td><td>Indent using spaces<br>Indentation size: 2</td></tr>
+ <tr><td>Ant -> Editor -> Formatter</td><td>Tab size: 2<br>Use tab character instead of spaces: unchecked</td></tr>
+</table>
+
+<p>
+The recommended configuration of Compiler Warnings is documented in
+<code>res/ide-support/eclipse/java-compiler-errors-warnings.txt</code> file.
