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

Question

我遇到了部署appengine的問題。在應用部署結束後，我收到以下錯誤

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

得到部署應用程序，但如果我運行這個版本，我得到的問題，我的數據得到下面的錯誤日誌。

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. 

我在更新Google eclipse插件之前沒有這個問題。

不期望的修正。我已經下載了新的Eclipse 3.7.2並重新安裝插件。
