I'm making an ant build file and I'm required to make it use a "jar" target command. That was the easy part. The hard part is, after the jar is created, I need to delete the META-INF directory that is made automatically in the jar. I tried adding a tag but that ended up running, yet doing absolutely nothing. I even tried adding defaultexcludes="no"/> at the end of the tag but I had the same result. Any insight on how to do this?
