When I run an Execute shell build step to execute a script and that script returns 0, Jenkins flags the build as SUCCESS, otherwise it flags it as FAILURE which is the expected default behaviour as 0 means no errors and any other value represents an error.
Is there a way to mark a build as SUCCESS only if the return value matches a specific value other than 0 (e.g. 1,2,3...)?
PS: in case you're wondering why I'm looking for that, this will allow me to perform unit testing of Jenkins itself as my scripts are written to return different exit values depending on various factors, thus allowing me to expect certain values depending on certain setup mistakes and making sure my whole Jenkins integration picks up on those.
All right, I went on IRC #jenkins and no-one new about a plugin to set a particular job status depending on a particular exit code :( I managed to do what I wanted by creating an Execute shell step with the following content:
bash -c "/path/to/myscript.sh; if [ "\$?" == "$EXPECTED_EXIT_CODE" ]; then exit 0; else exit 1; fi"
-Running the script under bash -c allows catching the exit code and prevents Jenkins from stopping build execution when that exit code is different than 0 (which it normally does).
-\$? is interpreted as $? after the script execution and represents its exit code.
-$EXPECTED_EXIT_CODE is one of my job parameters which defines the exit code I'm expecting.
-The if statement simply does the following: if I get the expected exit code, exit with 0 so that the build is marked as SUCCESS, else exit with 1 so that the build is marked as FAILURE.
/path/to/myscript.sh || if [ "$?" == "$EXPECTED_EXIT_CODE" ]; then continue; else exit 1; fi
I would use continue instead of exit 0 in case you have other items below that you need to run through.
Can handle it via the Text-finder Plugin:
- Have your script print the exit-code it is about to exit with, like:
Failed on XXX - Exiting with RC 2
- Use the Text-finder Plugin to catch that error-message and mark the build as 'Failed' or 'Unstable',
for example, if you decide RC 2, 3 and 4 should mark the build as 'Unstable', look for text in this pattern:
Exiting with RC [2-4].
Create a wrapper for your shell script. Have that wrapper execute your tests and then set the resturn value according to whatever criteria you want.
I do it like this:
set +e
./myscript.sh
rc="$?"
set -e
if [ "$rc" == "$EXPECTED_CODE_1" ]; then
#...actions 1 (if required)
exit 0
elif [ "$rc" == "$EXPECTED_CODE_2" ]; then
#...actions 2 (if required)
exit 0
else
#...actions else (if required)
exit "$rc"
fi
echo "End of script" #Should never happen, just to indicate there's nothing further
Here +e is to avoid default Jenkins behavior to report FAILURE on any sneeze during your script execution. Then get back with -e.
So that you can handle your exit code as appropriate, else eventually FAIL with the returned code.
robocopy "srcDir" "destDir" /"copyOption" if %ERRORLEVEL% LEQ 2 exit 0
If robocopy exit code is less than or equal to 2 then it will exit successfully.
Robocopy Exit Codes:
0×00 0 No errors occurred, and no copying was done.
The source and destination directory trees are completely synchronized.
0×01 1 One or more files were copied successfully (that is, new files have arrived).
0×02 2 Some Extra files or directories were detected. No files were copied
Examine the output log for details.
0×04 4 Some Mismatched files or directories were detected.
Examine the output log. Housekeeping might be required.
0×08 8 Some files or directories could not be copied
(copy errors occurred and the retry limit was exceeded).
Check these errors further.
0×10 16 Serious error. Robocopy did not copy any files.
Either a usage error or an error due to insufficient access privileges
on the source or destination directories.
