I have this same issue on Windows. Everything works fine when using a self-extracting jar. When I try to run from a non-extracting jar, ant cannot find the location of the jar.
I've tried using the antinstaller-jar property - it is not being set. The builddir property is set to the location of the temp directory.
What am I missing?
Thanks.
