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



 消息:
意外异常

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.
