[news.eclipse.platform] Re: No solution found because the problem in /tm

[Andrew Niefer <aniefer@xxxxxxxxxx>]

The problem is unsatisfiable means that p2 can't find a set of plugins 
that satisfies all the requirements.  If you look at the errors one at a 
time, it really isn't that hard.  (The hard part would be finding the 
root cause).

This means that you are asking to install both of
	org.eclipse.equinox.preferences_3.2.201.R34x_v20080709
and	org.eclipse.equinox.preferences_3.2.200.v20080421-2006
But they can't both exist in the same install, which would be because 
org.eclipse.equinox.preferences is a singleton bundle.

This means the bundle org.eclipse.jst.j2ee.ejb requires a version of 
org.eclipse.emf.ecore between 2.2.0 and 2.4.0.

I expect org.eclipse.emf.ecore is a singleton, and those version ranges 
don't overlap, so there will never be a version of org.eclipse.emf.ecore 
that satisfies this.

More non-overlapping version ranges, there are a bunch of these.  And 
this is probably the root cause.  You are perhaps trying to install 
something old into a 3.4.0 eclipse, and that old thing has dependencies 
on a 3.2.0 eclipse.
