我正在使用this tutorial构建一个使用GAE的应用，我正在尝试按照here解释为类生成Cloud端点库。

但是，我遇到了意外错误。以下是详细信息：

我使用的Eclipse版本是4.3。

Answer 1

我面临同样的问题。但是，我找到了这个链接，我认为它可以帮助： 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，它告诉我们如何使用命令行创建端点库： https://developers.google.com/appengine/docs/java/endpoints/endpoints_tool

我正在研究这个解决方案。如果我得到任何好消息，我会更新。

Answer 2

如Google Bugtracker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 见：https://code.google.com/p/google-plugin-for-eclipse/issues/detail?id=278
