cannot create a class in an Android project #1616

Closed scabug closed 13 years ago

scabug commented 15 years ago

I installed the latest Eclipse 3.4 and latest released Scala plugin, and the Android development plugin. I created an Android project from scratch and that worked.

I then tried to add a Scala class and could not. Specifically, I added Scala Nature to the project, switched to the Scala perspective, right clicked on a package in the Package Explorer, and selected "New -> Scala Class". The dialog popped up, I typed in a class name, and when I hit finish nothing apparent happens. I realized that Error Log entries are being created when I try, though. Doubling clicking on one of the Error Log entries, I see the following stack trace.

@milessabin said: How did you add the Scala Nature? Did you do it by manually editing the .project file? If so could you try again with a fresh Android project and let me know if the problem goes away if you close and reopen the project before attempting to add any Scala classes to the project.
