Hi,
Your best bet is to debug it with Eclipse but NOT using the Eclipse
junit tool.
Change the ant junit target, add these jvmargs to the junit target
<junit ...>
<!-- To be added -->
<jvmarg value="-Xdebug" />
<jvmarg value="-Xnoagent" />
<jvmarg value="-Djava.compiler=NONE" />
<jvmarg
value="-Xrunjdwp:transport=dt_socket,address=8787,server=y,suspend=y" />
</junit>
Here I am using 8787 port for debugging which should be a free port on your
machine.
When the ant reaches this task, it will wait (because suspend=y), now from
Eclipse, launch a "Remote Java Application" debug with Connection Properties
set as localhost and 8787. Set breakpoints wherever required.
Hope this helps!
