Answer 1

Just as the message says, you need to use rollback command to undo the previous update that failed to complete. Just replace the word update with the word rollback (everything else stays the same) and run the command.

You can run it in the terminal window (command prompt) on your computer by running appcfg program.

Answer 2

In the terminal:

appcfg.py rollback (filename).yaml

Answer 3

If you are using maven, you can use rollback goal:

mvn appengine:rollback

Answer 4

In java, windows and eclipse:

Check the path for you appengine-java-sdk, in my case, it look like some things as.

 C:\Users\camno\.p2\pool\plugins\com.google.appengine.eclipse.sdkbundle_1.9.30\appengine-java-sdk-1.9.30\bin

Now in the console, go to the location of sdk, by type:

 cd [your appengine-java-sdk path]

Next, you can type the command for rollback:

appcfg -e [[email protected]] rollback [path to war of proyect]

The characteres [ ] must be no include. You can find more info about the comman arguments in https://cloud.google.com/appengine/docs/java/tools/appcfg-arguments
