更新代码 出现 You need to upgrade the working copy first 错误

今天更新了Eclipse的subclipse插件，更新代码报如下错误:

svn: The working copy at 'E:\591woospace\kst_fashion_alipay_v1.2.0\src\com\kstapp\wanshida\custom' is too old (format 10) to work with client version '1.8.8 (r1568071)' (expects format 31). You need to upgrade the working copy first.

 

 

解决方法：

直接去对应的文件夹，把名为".svn"的 隐藏文件夹删掉，重新同步就可以提交了
