Any progress on this? Generating a hash is fairly simple with ant: <target name="generate-checksum"> | <checksum algorithm="SHA1" todir="target/generated/hashes" totalproperty="archive-hash"> | <fileset dir="target/generated"> | <exclude name="**/hashes/**" /> | </fileset> | <fileset dir="target/classes" /> | </checksum> | <echo message="Archive-Hash: ${archive-hash}" file="target/generated/META-INF/archive-hash.sha1" /> | </target> View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3964782#...
