我正在使用本教程构建一个使用 GAE 的应用程序，并且我正在尝试为一个类生成一个云端点库，如此处所述。

但是，我遇到了一个意外错误。以下是详细信息：

我面临同样的问题。但是，我找到了这个链接，我认为它可以提供帮助： http: //mall.51zks.com/Problem/index/-190279264/generating-the-api-metadata-for-cloud-endpoints-classes-failed/

它基本上链接到此链接，该链接也说明如何使用命令行创建端点库： https ://developers.google.com/appengine/docs/java/endpoints/endpoints_tool

我现在正在研究这个解决方案。如果我有任何好消息，我会更新。

如 Google bugtracker 中所述，这是一个已知错误，您必须降级到 1.9.3 或将插件工具升级到 3.6.0，请参阅：https ://code.google.com/p/google-plugin-for-eclipse/issues /detail?id=278
