greggh,
I am not aware of any discovery mechanisms (double clicking to jump to problem). I would check the project references that your current project has, note them, then open all of those projects and see if they depend on your problomatic project to see if that is casuing the problem.
Oddly enough, I’ve also recieved errors of circular reference from the Eclipse compiler when infact the problem was that I was missing JARs in the build path so my project wouldn’t build correctly. You can load up your project properties, and check the build patch and hit “Add JARs” to see if there were any JARs you forgot to add to the project to allow it to build correctly.
