用SVN上传war时，最后SVN Commit上传war包到服务器失败，出现下面语句：
Commit blocked by pre-commit hook (exit code 1) with output:
ERROR: invalid directory or file: gfs.hhu.edu.cn.war
This error was generated by a custom hook script on the Subversion server.
Please contact your server administrator for help with resolving this issue.
