Java classes won't open in Eclipse

Question

I've tried cleaning and validating my project, restarting both Eclipse and my computer and my java class files won't open in the editor. Also, I've tried deleting the project from my workspace and reimporting it and no luck. Does anyone know what it might be?

Make sure you are in the Java perspective.

Try cleaning eclipse. Start eclipse with

eclipse --clean
