How to mark Jenkins builds as SUCCESS only on specific error exit values (other than 0)?

Question

When I run an Execute shell build step to execute a script and that script returns 0, Jenkins flags the build as SUCCESS, oth

Answer 1

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.
