Re: [Subclipse-dev] Building Subclipse with Hudson/Buckminster

A quick question I have ...

When I build Subclipse for release, I do it using a copy of Eclipse
3.2 that I leave lying around. Is this still possible using
Buckminster? Obviously the build process could run with something
newer, but the classes it is resolving against when it compiles need
to be Eclipse 3.2 for proper backwards compat. at least that is what
I always thought.
