google eclipse 3.7 插件 2.6.0.v201205021203-rel-r37 jpa 问题

Question

我在部署 appengine 时遇到问题。在应用程序部署结束时，我收到以下错误

An internal error occurred during: "Deploying My GWT AppEngine to Google".
org/eclipse/jpt/jpa/core/JpaProject

应用程序已部署，但如果我运行该版本，我的数据会出现问题，获取以下错误日志。

The class "The class "com.example.mygwt.engine.bean.Bean" is not persistable. 
This means that it either hasnt been enhanced, or that the enhanced version 
of the file is not in the CLASSPATH (or is hidden by an unenhanced version), 
or the Meta-Data/annotations for the class are not found." is not persistable. 

在我更新 google eclipse 插件之前我没有这个问题。

不是想要的修复。我已经下载了新的 eclipse 3.7.2 并重新安装了插件。
