java.io.ioexception failed to mkdirs jenkins xcode || jenkins 无法创建新文件

===========================================================
FATAL: Failed to mkdirs: /Users/chenqing/Sqy/iOSProject/cyou/Svn/Cos/CosXCode_lxh/test-reports
java.io.IOException: Failed to mkdirs: /Users/chenqing/Sqy/iOSProject/cyou/Svn/Cos/CosXCode_lxh/test-reports
	at hudson.FilePath.mkdirs(FilePath.java:1093)

在用jenkins 集成的时候遇到这个错误 。。
解决办法：修改文件的读写限制
输入命令查看# ls -l   发现无法写入

drwxr-xr-x  22 chenqing  staff      748 Aug 21 18:05 Classes
-rw-r--r--   1 chenqing  staff  1035851 Aug 21 18:05 Default-568h@2x.png
.......
drwxr-xr-x   8 chenqing  staff      272 Aug 22 14:11 Unity-iPhone.xcodeproj
drwxrwxrwx   2 chenqing  staff       68 Aug 22 14:35 dirname

输入命令#chmod -R 777./   

再次查看时

drwxrwxrwx  22 chenqing  staff      748 Aug 21 18:05 Classes
-rwxrwxrwx   1 chenqing  staff  1035851 Aug 21 18:05 Default-568h@2x.png
.....

drwxrwxrwx   8 chenqing  staff      272 Aug 22 14:11 Unity-iPhone.xcodeproj
drwxrwxrwx   2 chenqing  staff       68 Aug 22 14:35 dirname

这时就正常了。。再次回到jenkins 编译 不会再出现
