that's exactly what i want to do. i'm just writing my own plugin which does following: -) fetch new artifact jar -) fetch old artifact jar
use java.util.zip.Zipfile to get all entries and compare their crc's. if the file changed or was not present in old artifact, add the file; if entry is not present in new artifact, but in the old one mark it as deleted. deleted files are a bit tricky because it should be possible to upgrade from v1.0 to v1.3; so i have to know all files which have been deleted between those versions. because of that i can't only compare two versions of a artifact but all versions between. but it seems to work for me.
