[shell] Execute Shell Script after post build in Jenkins

I am trying to execute a shell script if either the build pass or fails after post-build in Jenkins. I cannot see this option in post build to execute some shell script except for running a target.

You'd have to set up the post-build shell script as a separate Jenkins job and trigger it as a post-build step. It looks like you will need to use the Parameterized Trigger Plugin as the standard "Build other projects" option only works if your triggering build is successful.

If I'm reading your question right, you want to run a script in the post build actions part of the build.

I myself use PostBuildScript Plugin for running git clean -fxd after the build has archived artifacts and published test results. My Jenkins slaves have SSD disks, so I do not have the room keep generated files in the workspace.

You can also run arbitrary commands using the Groovy Post Build - and that will give you a lot of control over when they run and so forth. We use that to run a 'finger of blame' shell script in the case of failed or unstable builds.

if (manager.build.result.isWorseThan(hudson.model.Result.SUCCESS)) {
  item = hudson.model.Hudson.instance.getItem("PROJECTNAMEHERE")
  lastStableBuild = item.getLastStableBuild()
  lastStableDate = lastStableBuild.getTime()
  formattedLastStableDate = lastStableDate.format("MM/dd/yyyy h:mm:ss a")
  now = new Date()
  formattedNow = now.format("MM/dd/yyyy h:mm:ss a")
  command = ['/appframe/jenkins/appframework/fob.ksh', "${formattedLastStableDate}", "${formattedNow}"]
  manager.listener.logger.println "FOB Command: ${command}"
  manager.listener.logger.println command.execute().text
}

(Our command takes the last stable build date and the current time as parameters so it can go investigate who might have broken the build, but you could run whatever commands you like in a similar fashion)

You should be able to do that with the Batch Task plugin.

1. Create a batch task in the project.
2. Add a "Invoke batch tasks" post-build option selecting the same project.

An alternative can also be Post build task plugin.
