I'm trying to upgrade from JBT 3.1.0.-M4 to the latest. The problem is that JBT consists of many plugins. It would be easier if all the names started with "JBoss Tools", for example, Hibernate Tools is part of JBT but that may not be obvious. So I selected anything that I think may be related to JBT. But I'm keeping my existing version of m2e due to this bug in 0.10.0: https://issues.sonatype.org/browse/MNGECLIPSE-2155
It would be nice to be able to revert updates (I just figured that one out: Eclipse Installation details --> select previous configuration --> click revert button) Cool.
JBT plugins are now all 3.1.0.GA!
