If you have the google app engine plugin just click on the deploy button and it will re-deploy the whole application.

1. Update the version number in appengine-web.xml.
2. Re-deploy using the Google App Engine Eclipse plugin.
3. Go to the Admin console and set the new version as the default.

Voilà! You have just updated your app!
