Can't build WOLips since moving to Lion

I finally moved to Lion two days ago, and now I'm trying to build =
WOLips, but it fails while looking for the =
com.jprofiler.integrations.eclipse.internal.ProfilingSession. I see that =
this class exists, but in it's inside internal.A.ProfilingSession, not =
internal.ProfilingSession. It was working fine before I moved to Lion, =
so I guess it might be a problem with ant 1.8 (from memory, SL was using =
1.7)?

The error:
