GAE: [Your working directory, (*) is not equal to your application root (*)]解决方法

在Eclipse中使用App Engine插件启动GAE Server的时候，出现如下警告信息：

2009/09/14 4:30:19 com.google.appengine.tools.development.IsolatedAppClassLoader checkWorkingDirectory
警告: Your working directory, (***) is not equal to your 
web application root (***\war)
You will not be able to access files from your working directory on the production server.

 

解决方法：

1. 依次打开【Menu -> Run -> Run Configurations -> Web Application】
2. 选择当前的应用，并切换到【Arguments】栏
3. 将【Working Dirctionary】的值设置成【Other】：
   

   ${workspace_loc:***/war}
