I'm trying to build a copy of HelloWorlds in SpringSource Tool Suite and I can't seem to shake this error, any clues?

"The return types are incompatible for the inherited methods Repository<World,Long>.count(), CRUDRepository<World>.count()"

I'm trying to link to the 2.0.0 RC 1 libraries, or even from built source from:
