Google Cloud /标准Appengine：本地运行的应用程序失败

我使用Google Cloud / Java / Standard AppEngine开始了一个新项目。这个非常简单的项目包含根据Google Cloud Endpoints框架的端点/ API。在云上运行时，一切都按预期工作。在本地运行时，它根本不启动，我在下面得到了这个例外：

我从Eclispe / Windows 7开始我的本地服务器。根据堆栈跟踪，它在处理Oauth2时会崩溃（API不受限制，但它引用了一些安全对象）。

我一直在谷歌上搜索这个问题而一无所获。我有另一个没有任何端点的示例项目在Windows上正常运行。下面是我的pom.xml

有人可以帮忙吗？

谢谢。

答案 0 :(得分：0)

在发布我的问题之后，我仔细检查了一下，注意到我忘了按照教程

中的说明执行以下命令 
gcloud auth application-default login

现在，它开始了。感谢任何试图提供帮助的人。
