This has been answered many times, but I had issues getting it to work for me too. If you are running Java and are also having problems or if you have Google's 2 factor authentication setup and that is giving you problems, here are the steps I used to make it succeed:

1) Make sure you have the Google App Engine in your Path in Environment variables. IE: C:\Users\yourUserName\Desktop\Eclipse\plugins\com.google.appengine.eclipse.sdkbundle_1.9.18\appengine-java-sdk-1.9.18\bin

2) Open up a command window AS AN ADMINISTRATOR! Do not just type cmd and enter, you need to type cmd, right-click on it, and open as admin

3) First, CD to the folder that has the WAR file in it. In my case, that was: cd "C:\Users\yourUserName\Documents\MyWorkspace\Project1" This is the same folder that has the src, .settings, and war folders in it.

4) In the cmd window, type: "appcfg rollback war" and press enter.

5) It will ask for your google credentials. If you do not have 2 factor authentication setup, simply type them in and press enter and you will be set.

6) If you DO have 2 factor authentication setup, go to your google accounts page (Just google for 'google account') and it will be the first or second one. Next, under the "Signing In" category, go to App passwords. Next, go to the bottom and under the select app dropdown menu, choose other and type in anything (IE: GAE rollback) It will give you a password (16 digit random numbers). Finally, type in your email address in the command window and then type/ paste in this new temporary 16 digit password into the password section.

7) Profit!
