Robocopy Errorlevel Return Codes (found in robocopy.doc)

The return code from Robocopy is a bit map, defined as follows:

0×10 Serious error. Robocopy did not copy any files. This is either a usage error or an error due to insufficient access privileges on the source or destination directories.
0×08 Some files or directories could not be copied (copy errors occurred and the retry limit was exceeded). Check these errors further.
0×04 Some Mismatched files or directories were detected. Examine the output log. Housekeeping is probably necessary.
0×02 Some Extra files or directories were detected. Examine the output log. Some housekeeping may be needed.
0×01 One or more files were copied successfully (that is, new files have arrived).
0×00 No errors occurred, and no copying was done. The source and destination directory trees are completely synchronized.

如果使用hudson、cruisecontrol之类的软件使用robocopy，由于robocopy正常拷贝下返回值不是0，这些软件都会报错。因此，使用如下语句进行重设置返回值：

if %ERRORLEVEL% LEQ 7 set ERRORLEVEL=0

或者单独设置

if ERRORLEVEL 1 set ERRORLEVEL=0
if ERRORLEVEL 2 set ERRORLEVEL=0
if ERRORLEVEL 3 set ERRORLEVEL=0 
if ERRORLEVEL 5 set ERRORLEVEL=0 
if ERRORLEVEL 6 set ERRORLEVEL=0 
if ERRORLEVEL 7 set ERRORLEVEL=0
