Application for gae does not deploy

Question

I don't remember going through the process of finding a unique Application name. If that is the problem (that the name I chose was not new) can someone remind me how to start that process unless the ERROR message below is suggesting some other problem.

I am pretty sure I have not uploaded this application before, so maybe "update" is not appropriate. I clicked the "Deploy" button on my SDK window to start this process, btw.

*** Running appfg.py with the following flags:
    --no_cookies --email=[e-mail] --passin update

Answer 1

Follow the instructions in the "Registering Your Application" section in the Getting Started guide for Java or Python.

Answer 2

I removed ~/.appcfg_oauth2_tokens_java and it solved my problem. Also, it's worth check out this link https://cloud.google.com/appengine/docs/java/tools/uploadinganapp

The unique application name is selected when you create a new project on the appengine website. If you have not done that yet, go do find your application name/create your account. Also, make sure you are signed into google in Eclipse. It should say your google account name at the bottom left corner.
