Post steps

• Runs after a stage has finished executing
• Runs after a pipeline has finished executing

Can run when:

• Always - even if the steps before the post steps fail, the post steps will always run
• Failed - runs only when the proceeding steps have failed
• Success - runs only when the proceeding steps have passed
• unstable - runs only when the proceeding steps have been marked as unstable
• changed - runs only when the state has changed relative to the previous run
  • e.g. stage "foo" was success in run 1, then fails in run 2 would these steps ever be run

Example

pipeline {
    agent any
    stages {
        stage('No-op') {
            steps {
                sh 'ls'
            }
        }
    }
    post {
        always {
            echo 'One way or another, I have finished'
            deleteDir() /* clean up our workspace */
        }
        success {
            echo 'I succeeeded!'
        }
        unstable {
            echo 'I am unstable :/'
        }
        failure {
            echo 'I failed :('
        }
        changed {
            echo 'Things were different before...'
        }
    }
