I'm probably doing things incorrectly.

The code snippet is...

Target target = (Target)getProject().getTargets().get(fromTarget);
Task[] tasks = target.getTasks();

Then I just search through the array for the one labeled "java" and
that turns out to be an UnknownElement.

Basically, all I want to do is get a reference to some java task that
will allow me to extract the classpath and jvm arguments so I can just
output those to a shell script.

Thanks for your help.
