在GAE中创建Google Cloud Endpoint时的项目错误（Eclipse）

问题描述

限时删除！！

我用GAE创建了一个简单的项目，并将我的包模型放在PMF.java（Persistence Manager Factory Class）和一个类（Employee.java）中。
右键单击Google-> Generate Cloud Endpoint Class上的Employee类，插件会正确生成EmployeeEndpoint，但在创建后会出现以下错误：

  war-> WEB-INF-> lib 
  

为此jar：

  appengine-api-labs.jar 
 appengine-endpoints.jar 
 appengine -endpoints-deps.jar 
  

打开Eclipse的ErrorLog，它只是说：

 异常堆栈跟踪不可用
  

所以点击项目：Google->生成云端点客户端库出现错误：

 错误在生成客户端库
  

与此消息：

 尝试生成客户端库时发生错误
  

所以，现在我面临这个错误，我能做些什么来解决这个问题？非常感谢您提前

解决方案

1）清洁项目2）关闭所有项目3）重新打开项目4）重新关闭项目5）关闭并重新打开Eclipse 6）打开项目7）清洁项目8）尝试生成Cloud Endpoint，现在可以使用 - 这是愚蠢的，但不像Eclipse那么愚蠢。

I created a simple project with GAE and i put in my package 'model' the PMF.java (Persistence Manager Factory Class) and a class (Employee.java).After right-clicking the Employee class on Google->Generate Cloud Endpoint Class, the plugin correctly generate my EmployeeEndpoint, but after created that it appears an error on:

war->WEB-INF->lib

for this jar:

appengine-api-labs.jar
appengine-endpoints.jar
appengine-endpoints-deps.jar

And opening the ErrorLog of Eclipse, it just says:

An exception stack trace is not available

So clicking on the project to: Google->Generate Cloud Endpoint Client Library an error appears:

Error in Generating Client Libraries

with this message:

An error occurred when attempting to generate the client libraries

So, now that i'm facing this error, what could i do to solve the problem? Thank you so much in advance

[EDIT Error Log]:

Message:
Unexpected Exception

解决方案

1) clean Project 2) Close All Projects 3)Re Open project 4) re-close project 5)closing and re-opening Eclipse 6)Open the project 7) Clean project 8)re try to generate Cloud Endpoint, and now works -.-" This is stupid, but not as stupid as Eclipse.
