Xtext Project Builder errors !?

[Dan White]

Errors running builder 'Xtext Project Builder' on project '20-manifests'.
org.eclipse.core.internal.preferences.EclipsePreferences.internalFlush()V

And I have a lot of red flags on my files complaining of unknown class references and such.

No clue where to start looking.
Any one got a clue for this clueless one ?

For starters, make sure you have the latest update - one was published
as late as yesterday - it contains a fix for a Null Pointer Exception
that could occur for certain combinations of syntax errors.

Otherwise, the checklist is:
1. Is puppet nature turned on for your project
2. Are your files on the puppet path ?
3. Are files in projects (direct, or linked), or did you do some kind of
file open?
4. Do you have everything in one project, or different projects in
different modules? (If so, the visibility is controlled by the
dependencies listed in the Modulefiles.
5. Perhaps obvious: Do you actually have the classes you get errors for
in the files you are working with.
6. Close all open editor tabs, do a build clean.

If you can't figure it out... if your puppet logic is available in a
public git repository I could take a look to see what is going on.

One more thing, If you see an error with a stack trace, it would be
great if you can send that. You may still have it in Geppetto's log.
