java - Google App Engine モジュールの更新

Question

Google App Engine モジュールを更新しようとすると、名前とバージョンが既に使用されているというエラーが表示されます (更新しようとしています)。更新したいモジュールだけでなく EAR 全体を更新しようとしましたが、どちらも同じエラーが発生します。

Unable to update:
com.google.appengine.tools.admin.HttpIoException: Error posting to URL: https://appengine.google.com/api/appversion/create?module=stomp&app_id=<my_app_id>&version=stomp&
400 Bad Request
Version 'stomp' is already in use as a module name. Please use a different version.
