[dash-dev] using -listener with org.eclipse.core.antRunner

[Jacek Pospychala <jacek.p@xxxxxxxx>]

hi,

I want to get some data what are the most time consuming tasks in my PDEBuild based build.
Because we already use ant-contrib, I thought of using their performance monitor, which usually is invoked with

ant -listener net.sf.antcontrib.perf.AntPerformanceListener target

However when using java -jar equinox.launcher -application o.e.core.antRunner it obviously doesn't work for class-loading reasons.
I tried some simple hacks, like java -cp lib\ant-contrib.jar, or setting the CLASSPATH=lib\ant-contrib.jar, I also looked at org.apache.tools.ant.AntClassLoader which seems to take different approach for org.apache.ant.* classes vs. other classes. But still no progress.

Anyone had more success with monitoring their PDEBuild based builds? :-)


thanx

Jacek


For reference here's class-loading exception I'm getting:
