I hit F5 ~1000 times and restarted eclipse (also with -clean), deleted /bin, but nothing helps. Manually importing DoodleClient does not help. DoodleClient exists and is perfect
I have 3 projects in my project explorer and they have dependencies on each other.
They all went nuts and I had 9000+ errors across all 3 projects.
It turned out that cleaning each of them in the correct order (middle, top, bottom) resolved everything.
Cleaning in the correct order is what fixed my issue.
Just thought it was worth mentioning :)
