Hi,
I'm writing a patch to maven-jar-plugin. The code compiles fine, and
runs the tests ok. However it fails shortly after, with a message I
can't understand.
I suspect the failure is in the "package" phase, when running the "jar"
goal to create a jar. Rather ironic :-)
The version I'm building is 2.1-snapshot. I'm using maven-2.0.4 to do
the build.
Any suggestions on how to resolve this are very welcome.
