Cleaning up and notifications

Since the post section of a Pipeline is guaranteed to run at the end of a Pipeline’s execution, we can add some notification or other steps to perform finalization, notification, or other end-of-Pipeline tasks.

Jenkinsfile (Declarative Pipeline)
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...'
        }
    }
}
Toggle Scripted Pipeline (Advanced)

There are plenty of ways to send notifications, below are a few snippets demonstrating how to send notifications about a Pipeline to an email, a Hipchat room, or a Slack channel.

Email

post {
    failure {
        mail to: 'team@example.com',
             subject: "Failed Pipeline: ${currentBuild.fullDisplayName}",
             body: "Something is wrong with ${env.BUILD_URL}"
    }
}

Hipchat

post {
    failure {
        hipchatSend message: "Attention @here ${env.JOB_NAME} #${env.BUILD_NUMBER} has failed.",
                    color: 'RED'
    }
}

Slack

post {
    success {
        slackSend channel: '#ops-room',
                  color: 'good',
                  message: "The pipeline ${currentBuild.fullDisplayName} completed successfully."
    }
}

Now that the team is being notified when things are failing, unstable, or even succeeding we can finish our continuous delivery pipeline with the exciting part: shipping!
