Are dependencies to SWT properly setup in your project?

Hi

Have you restarted Eclipse and cleaned and rebuilt everything.?

Have you checked the target definition? The new PDE *.target editor tooling makes it really easy to trash the target definition and thereafter all sorts of magic stupid errors happen.

Regards

@Aaron, for a systematic analysis it might help, if first you describe to us, by which means JDT should resolve those references? We don't even know if your's is a plug-in project or a plain Java project. Are the desired plug-ins correctly showing as dependencies (in the Java Build Path dialog and/or the Package Explorer) etc. pp.

Before we know these things we can only provide hints of the style of cargo cult ;p (i.e., actions that empirically have solved problems in the past, without knowing their root cause).
