Delete Cached Google App Engine Credentials

If you specify wrong email address when you update Google App Engine application you might lock your self out for some time. That happened to me today when I was deploying application to company’s GAE account but by mistake logged in my private Google credentials. Obviously, failed early and did not upload application but I could not start upload even after I retried specifying  –email option with valid email (I would consider this Google’s bug).

Anyway, I recovered after finding and deleting the following two files in my home folder:


(I’m not sure if deletion of the second file was necesarry.)

Hope this helps someone.
