This can easily be done: - http://anonsvn.jboss.org/repos/jbossas/projects/jboss-deployers/trunk/dep... See the usage of hasRootBeenModified(VirtualFile root). Although I wrote this stuff I don't know why we didn't include this in the first place. I guess there was a reason, which looks like it slipped my mind. :-( But instead of this touch hack, we could provide a different StructureModificationChecker, for those who rely on .class changes. It would check classes as well as metadata locations. View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4244285#...
