IMPORTANT: This is not a supported means of building Tomcat; this information isprovided 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.

1. Download Apache Ant 1.10.7
2. Apache Ant 1.8.2
3. Apache Ant 1.7 0 Download Torrent
4. Apache Ant 1.7.1

NOTE: This will not let you build everything under Eclipse;the build process requires use of Ant for the many stages that aren'tsimple Java compilations.However, it will allow you to view and edit the Java code,get warnings, reformat code, perform refactorings, run Tomcatunder the IDE, and so on.

Download Apache Ant 1.10.7

WARNING: Do not forget to create and configure ${tomcat.source}/build.properties file as described above before running any Ant targets.

Apache Ant 1.7.0 December 19, 2006 - Apache Ant 1.7.0 Available. Apache Ant 1.7.0 is now available for download. Ant 1.7 introduces a resource framework. Some of the core ant tasks such as are now able to process not only file system resources but also zip entries, tar entries, paths. Apache Ant 1.6.5 (or newer, 1.7.0 should work as well) To run samples included in the binary distribution of Apache CXF, you must install the Apache Ant 1.6.5 build utility, which can be downloaded.

Sample Eclipse project files and launch targets are provided in theres/ide-support/eclipse directory of the source tree.The instructions below will automatically copy these into the required locations.

• This page shows details for the JAR file ant-1.7.0.jar contained in org/apache/ant/ant/1.7.0. Apart from vendor, name and version also the contained classes and JAR.
• Apache Ant version 1.7. 0 compiled on December 13 2006 Download the.zip file of the Winter '21 Ant Migration Tool. The download link doesn’t require authentication to Salesforce.

Two Ant targets are provided as a convenience. The first one, namedide-eclipse, downloads all binary dependencies and configuresEclipse project in the root of the source tree. The created Eclipse projecttargets a Java 6 JDK and skips WebSocket classes that cannot be compiled withJava 6.

The second target, named ide-eclipse-websocket, creates directory../tomcat-7.0.x-java7 and configures the second Eclipse projectthere. This project targets a Java 7 JDK. This project does not have its ownsource tree, but accesses a subset of the source tree of the first project,compiling all WebSocket classes that were skipped.

cd ${tomcat.source}
ant ide-eclipse
ant ide-eclipse-websocket

Start Eclipse and create a new Workspace.

Open the Preferences dialog and then select Java->Build Path->ClasspathVariables to add two new Classpath Variables:

In the Preferences dialog go to Java->Installed JREsand add JDK 6 and JDK 7 there. Close the dialog.

Use File->Import command from menu and choose Existing Projects into Workspace.From there choose the root directory of the Tomcat source tree (${tomcat.source})and import the project located there. Import the second project as well,if you have created it (../tomcat-7.0.x-java7).

Apache Ant 1.8.2

start-tomcat and stop-tomcat launch configurations are provided inres/ide-support/eclipse and will be available in the Run->Run Configurationsdialog. Use these to start and stop Tomcat from Eclipse.If you want to configure these yourself (or are using a different IDE)then use org.apache.catalina.startup.Bootstrap as the main class,start/stop etc. as program arguments, and specify -Dcatalina.home=...(with the name of your build directory) as VM arguments.

Tweaking a few formatting preferences will make it much easier to keep consistent with Tomcatcoding conventions (and have your contributions accepted):
