svn出现恼人的cleanup failed，如下

svn cleanup failed–previous operation has not finished; run cleanup if it was interrupted

解决方法：清空svn的队列

1.下载 

2.找到项目所在.svn文件，找到wc.db

3.执行sqlite3 .svn/wc.db "select * from work_queue"

       看到很多记录，就是出问题的记录

4.下一步执行sqlite3 wc.db "delete from work_queue"

5.在出错目录下再次执行svn cleanup，完事
