Recently, I noticed that the robocopy and Jenkins were not playing nice. My jobs kept failing even though robocopy was succeeding.
Eventually I figured out that Jenkins was expecting an error code of 0 to be returned and robocopy was returning error code 1 (as a success).
The following screenshot explains everything. You will also find the workaround a bit further down in this post.
robocopy errorlevel causes a failed jenkins build
Wrong EOL (UNIX type: LF) in Windows batch files executed for build steps of type “Execute Windows batch command”
The quick fix, from superuser.com, is to run your robocopy like this:
(robocopy XXX YYY) ^& IF %ERRORLEVEL% LEQ 4 exit /B 0
I prefer something a bit fancier that:
- Authenticates to a network share
- Runs robocopy as shown above
- Comments the hell out of everything
Here’s a jenkins script I use:
REM -- Authenticate with deployment location-- REM -- net use DOES NOT NEED A DRIVE LETTER!! -- REM -- w00t!! REM -- net use \\
REM -- Sync to Destination -- REM -- Robocopy. If error level less than or equal to four-- REM -- Exit with "0" so jenkins passes the build-- (robocopy %WORKSPACE%\
\ \\ /mir /z /fp) ^& IF %ERRORLEVEL% LEQ 4 exit /B 0
