SubEclipse:Path is not a working copy directory

org.tigris.subversion.javahl.ClientException: Path is not a working copy directory

使用Eclipse3.7,安装完subeclips插件后，使用该插件进行svn代码更新没有问题，但进行提交时报错，
错误信息如下：
commit -m "add system test" D:/Email/emm/src/main/java/com/test/XXController.java
    Path is not a working copy directory
svn: Commit failed (details follow):
svn: '.' is not a working copy

解决方案：右击项目，选择Team-->Disconnect-->Also delete the SVN meta information from the file system.再到svn checkout目录重新checkout覆盖原项目。
