How to disable command output in jenkins pipeline build logs
By default Jenkins starts shell scripts with flags -xe. -x enables additional logging. -e makes the script exit if any command inside returns non-zero exit status. To reset a flag I'd suggest two options:
- Call
set +xin the body of your script. - Pass custom shebang line without
-x:sh('#!/bin/sh -e\n' + 'echo shellscript.sh arg1 arg2')
As for the second option you can define a wrapper function for convenience which will prepend the script with custom shebang and then call sh
def mysh(cmd) { sh('#!/bin/sh -e\n' + cmd)}
For instances where post processing is required. I extended the original solution provided here.
For example
def output = printWithNoTrace("ping -c 1 $FQDN | grep PING).trim()wrapper function
def printWithNoTrace(cmd) {steps.sh (script: '#!/bin/sh -e\n'+ cmd,returnStdout: true) }The shell output is returned to trim() and saved to "output"
