Not sure. I don't know Java very well and the package stuff was always confusing to me. The current SVN version has an improved build system which is much more flexible than before and probably could help you reaching your goal. It supports now also %d for the directory of the current file and %p for the project base directory Otherwise maybe you can just use a simple shell script which you use as run command and pass it the .class' filename and let the shell script do some magic to get the right path.
