Hello,
I want ant to generate heap dump when OutOfMemoryError happens during
the build to find the problem in the task. I tried adding following
switches to .antrc file: -XX:+HeapDumpOnOutOfMemoryError
-XX:HeapDumpPath=e:\ant.hprof
But it doesn't seem to get to the correct process, in other words -
nothing happens. Is there some other way to generate heap dump from ant.
I'm using Ant 1.6.5 on JDK 1.5.0_09.
If the problem is in Ant's own process, set the ANT_OPTS env variable to
the options.
If it is in some forked java process (like javac), you need to set the
options inside ant by whatever element the task offers to set JVM
options, usually <jvmargs>
