I just installed Eclipse and Android SDK in Mac OS X.
I imported the project to Eclipse and i get the Unknown command \'crunch\' error while running the project.
After updating to ADT r14, go to Window -> SDK Manager (in Eclipse)
Check on 'repository', uncheck "installed"
Wait for packages to load, then select all support packages, accept all and install them
Restart Eclipse
Run your apps on new ADT r14, without 'crunch' errors
Worked for me :)
