Post-build actions in Jenkins - Mini Project: Build & Apply

Jenkins Post-build Actions Setup

📖 Scenario: You are setting up a Jenkins job to automate a simple build process. After the build completes, you want Jenkins to perform some actions automatically, like archiving build artifacts and sending notifications.

🎯 Goal: Learn how to configure post-build actions in a Jenkins job using the Jenkinsfile syntax.

📋 What You'll Learn

Create a Jenkinsfile with a basic pipeline

Add a post-build action to archive artifacts

Add a post-build action to send a notification

Print confirmation that post-build actions are configured

💡 Why This Matters

🌍 Real World

In real projects, Jenkins post-build actions automate tasks like saving build outputs and notifying teams, saving time and reducing errors.

💼 Career

Understanding Jenkins post-build actions is essential for DevOps engineers to automate continuous integration and delivery pipelines effectively.

1

Create a basic Jenkins pipeline

Create a Jenkinsfile with a pipeline block that has an empty agent any and an empty stages block.

Jenkins

pipeline {
    agent any
    stages {
        // Your code here
    }
}

Need a hint?

Start with the basic Jenkins pipeline structure: pipeline { agent any stages { } }.

2

Add a post-build action to archive artifacts

Add a post block inside the pipeline with a always condition that uses archiveArtifacts to archive files matching "**/*.jar".

Jenkins

pipeline {
    agent any
    stages {
    }
    post {
        always {
            // Your code here
        }
    }
}

Need a hint?

Use post { always { archiveArtifacts artifacts: '**/*.jar' } } to archive all JAR files after every build.

3

Add a post-build action to send a notification

Inside the same always block in the post section, add a echo step that prints "Build completed - notifications sent".

Jenkins

pipeline {
    agent any
    stages {
    }
    post {
        always {
            archiveArtifacts artifacts: '**/*.jar'
            // Your code here
        }
    }
}

Need a hint?

Add echo 'Build completed - notifications sent' inside the always block to simulate sending a notification.

4

Print confirmation of post-build actions

Add a print statement in the Jenkinsfile script that outputs exactly "Post-build actions configured successfully".

Jenkins

pipeline {
    agent any
    stages {
    }
    post {
        always {
            archiveArtifacts artifacts: '**/*.jar'
            echo 'Build completed - notifications sent'
        }
    }
}

// Your code here

Need a hint?

Use print('Post-build actions configured successfully') outside the pipeline block to confirm setup.
