Subject Core ant project in Eclipse
Date Sat, 15 May 2010 22:46:00 GMT
All,

I have had a hard time finding information on running ant locally in Eclipse
so I can use the debugger to debug core ant code.

 Do the developers on the project typically use Eclipse for development?

If so, what class path works in Eclipse to do this?

Is there a set of commands to get all the dependent jars?

Can I debug org.apache.tools.ant.launch.Launcher directly?

If so, where should the build.xml be that it runs?

Below are the steps I have completed get this going.

I have checked out.
http://svn.apache.org/repos/asf/ant/core/trunk from subversion to a
directory called ant-core.
I got up to revision 944382 which is 1.8.2alpha.

I created a new Java Project against this code.
The default output folder is ant-core/bin.

The default Libraries are ant-antunit-1.1.jar, junit-3.8.2.jar and the JRE
(I'm currently using jdk1.6.0_14)

Eclipse detects the default source directories as the following:
ant-core/src
ant-core/src/etc/testcases/core/containerssrc
ant-core/src/etc/testcases/core/loaderref/src
ant-core/src/etc/testcases/taskdefs/apt
ant-core/src/etc/testcases/taskdefs/fixcrlf/expected
ant-core/src/etc/testcases/taskdefs/fixcrlf/input
ant-core/src/etc/testcases/taskdefs/manifestclasspath
ant-core/src/etc/testcases/taskdefs/optional/depend/src1
ant-core/src/etc/testcases/taskdefs/optional/depend/src2
ant-core/src/etc/testcases/taskdefs/optional/depend/src3
 ant-core/src/etc/testcases/taskdefs/optional/depend/src4
ant-core/src/etc/testcases/taskdefs/optional/depend/src5
 ant-core/src/etc/testcases/taskdefs/optional/javah/input
 ant-core/src/etc/testcases/taskdefs/rmic/src
 ant-core/src/etc/testcases/taskdefs/types/assertions
ant-core/src/main
 ant-core/src/etc/tests/antunit/core/location/src
 ant-core/src/etc/tests/antunit/taskdefs/javac-dir/bad-src
 ant-core/src/etc/tests/antunit/taskdefs/javac-dir/good-src
 ant-core/src/etc/tests/antunit/taskdefs/optional/junit/src
ant-core/src/test/junit

This results in approximately 862 errors.
I was able to build.bat and it built the project into dist.

But, I would like to be able to use Eclipse's debugger.

The main launch point appears to be org.apache.tools.ant.launch.Launcher.

I can right-click on this file and select Debug Java application and hit
breakpoints I set, but I would need a clean build to do this.
