1. call ant target that produces generated sources within a source root
2. press "sync" button
3. modified files still not appearing
maybe it is of importance that the complete source route will be deleted and recreated by the ant script.
only restarting IDEA helps (and probably, to wait >some minutes).
Even close / reopen project does not help.
+ on another occasion I had the opposite case of IDEA showing files that were already deleted. (Even after close/reopen!)
This is quite disturbing - although I appreciate the modifications that suspectively were made in order to improve the behaviour of external drive scanning.
