Answer 1

I am facing the same problem. But, I have found this link and I think it can help: http://mall.51zks.com/Problem/index/-190279264/generating-the-api-metadata-for-cloud-endpoints-classes-failed/

It basically links forward to this link, which tells how to create the endpoint library using command line too: https://developers.google.com/appengine/docs/java/endpoints/endpoints_tool

I am working on this solution now. If I get any good news, I will update.

如Google Bugtracker中所述，这是一个已知的错误，您必须降级到1.9.3或将插件工具升级到3.6.0，请参见： https : //code.google.com/p/google-plugin-for-eclipse/issues /细节？ID = 278
