Why can't eclipse resolve class in same package?

Question

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

Answer 1

Tried many of the suggestions above w/o success (Eclipse restart, Clean multiple times, auto-suggest etc.). What got me out of this bind was a hard reset to a prior commit (I'm using git), building (this time w/ success), then pulling the latest sources of the project again and rebuilding.
