GAE appcfg rollback not working: 409 Conflict Another transaction by user is already in progress for app:

409 Conflict Another transaction by user XXX is already in progress for app: s~YYYY version: ZZ. That user can undo the transaction with "appcfg rollback".

Uploading a new version of the app on sep 23 2013 I got a 500 error. Since then I haven't been able to create new versions, I have followed the instructions by running: 

C:\tools\appengine-java-sdk-1.8.4\bin>**appcfg.cmd rollback** c:\Users\workspace-jee\WWW\war

I get:

If your app is built using Maven, the easier way to rollback is to point your terminal to the directory from where you run the appengine deployments, and type $appengine:rollback.

you need to run the rollback "project_War_Address" command in the appengine's sdk bin folder using cmd<>

"If you have any settings related to modules (< instance-class >, < automatic-scaling > etc.), please remove them, rollback the previous transaction and try deploying again."

Helps for me. Just removed "< automatic-scaling >" block and then "appcfg rollback".

Here is the solution provided by Cowen ATM

Google are aware of this issue and after following their advice, deployment was successful. their advice is copied below:

"We are aware of this issue where incorrect error message is displayed during deployment. If you have any settings related to modules (, etc.), please remove them, rollback the previous transaction and try deploying again."

Note: even if you have performed the rollback many times, you will need to perform it again AFTER removing the above mentioned settings from your appengine-web.xml file.

Same here. Please star this issue, since it seems to be a production problem given many of us are experiencing it: https://code.google.com/p/googleappengine/issues/detail?id=10021
