[亲测已解决]svn更新有问题svn: The working copy at' ' is too old

情景:  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.

原因：在svn是低版本时候checkout的项目 之后 我进行了升级了svn版本 然后 我再更新项目就出现如上问题

解决方法：如下图

控制台输出：The working copy needs to be upgraded 就对了
