The working copy needs to be upgraded svn: The working copy at

错误信息：

The working copy needs to be upgraded
svn: The working copy at 'F:\JAVA Project\PAW-VRVEIS-JJ-2.0\WebContent\WEB-INF\pages\applicationAddressAction'
is too old (format 10) to work with client version '1.8.14 (r1692801)' (expects format 31). You need to upgrade the working copy first.

我出现这个问题的原因是：我在把一个其他项目中的一个文件夹复制本项目中进行使用

最后发现这里有个svn

解决方法是把这个文件夹删除了，再加入到本项目
