I'm running Eclipse Indigo 64 bit on Windows 7 64 bit and I kept getting missing dependency errors associated with Maven and other plugins using the JBoss Tools 3.3.X latest download. Here is the link.
So, I opted to only install Hibernate Tools with nothing else by typing in "hibernate" at the top of the install software dialog in eclipse. Only 4 items showed up, so that is all I installed. It worked fine with no problems. Here is the tutorial that I used to get it installed properly after several failed attempts.
I don't know if part of this was due to having a lot of plugins already installed or if this is the best solution or not, but I thought I'd share it with everyone.
