我在 1.8.1 GAE for java 上使用 mac book pro mountain lion 上的 eclipse。
在尝试部署时出现错误: 无法更新:
com.google.appengine.tools.admin.HttpIoException: Error posting to URL: https://appengine.google.com/api/appversion/create?app_id=sakshumweb-hrd&version=3&
409 Conflict
Another transaction by user vik.ceo is already in progress for app: s~sakshumweb-hrd, version: 3. That user can undo the transaction with "appcfg rollback".

我已经执行了以下命令，该命令成功，但部署仍然失败并出现相同的错误。请注意，过去我已经完成了数百次，没有出现任何问题。

最佳答案
我遇到了同样的问题(没有 GWT)，我解决了部署 409 错误，谢谢 this answer 请尝试一下，从 appengine-web.xml 中删除实例类和自动缩放元素。
