Reprinted: svn error: Attempted to lock an already-locked dir solution

错误信息
Attempted to lock an already-locked dir    
svn: Working copy '***' locked  

Need to use the lock operation method of svn cleanup when it was last shut down :

1. Use svn client

 

2. Go directly to the .svn directory under the above folder and delete the lock file.
