Waiting for lock on /Users/MyName/Documents/play-2.1.3/repository/.sbt.ivy.lock to be         


        

Answer 1

Deleting the .lock file also works. But if you don't want to delete the lock file, you can unlock the file from the process which has the lock. If you are on windows, you can use a UI tool called "Unlocker" to do this (go to that file=>right click=>select unlocker).
