Build steps execution in Jenkins - Mini Project: Build & Apply

Build steps execution

📖 Scenario: You are setting up a Jenkins pipeline to automate a simple build process for a software project. The build process has multiple steps that need to run in order.

🎯 Goal: Build a Jenkins pipeline script that defines three build steps: checkout, build, and test. Each step should print a message indicating it is running.

📋 What You'll Learn

Create a Jenkins pipeline script using the pipeline and stages syntax

Define three stages named Checkout, Build, and Test

Each stage should have a steps block that prints a message using echo

The messages must be exactly: 'Checking out code...', 'Building the project...', and 'Running tests...'

💡 Why This Matters

🌍 Real World

Jenkins pipelines automate software builds, tests, and deployments in many companies to save time and reduce errors.

💼 Career

Understanding build steps execution is essential for DevOps engineers and automation specialists working with CI/CD tools like Jenkins.

1

Create the Jenkins pipeline skeleton

Write the initial Jenkins pipeline script with a pipeline block and an empty stages block.

Jenkins

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

Need a hint?

Start by writing pipeline { then specify agent any and add an empty stages { } block inside.

2

Add the Checkout stage

Inside the stages block, add a stage named Checkout with a steps block that uses echo to print 'Checking out code...'.

Jenkins

pipeline {
    agent any
    stages {
        // Add Checkout stage here
    }
}

Need a hint?

Use stage('Checkout') and inside it add steps { echo 'Checking out code...' }.

3

Add the Build and Test stages

Add two more stages inside stages: Build and Test. Each should have a steps block that prints 'Building the project...' and 'Running tests...' respectively using echo.

Jenkins

pipeline {
    agent any
    stages {
        stage('Checkout') {
            steps {
                echo 'Checking out code...'
            }
        }
        // Add Build and Test stages here
    }
}

Need a hint?

Add stage('Build') and stage('Test') with steps { echo ... } inside each.

4

Run the pipeline and display output

Print the entire Jenkins pipeline script so it can be run and shows the three messages in order.

Jenkins

pipeline {
    agent any
    stages {
        stage('Checkout') {
            steps {
                echo 'Checking out code...'
            }
        }
        stage('Build') {
            steps {
                echo 'Building the project...'
            }
        }
        stage('Test') {
            steps {
                echo 'Running tests...'
            }
        }
    }
}
// Your code here to run or print the pipeline script

Need a hint?

When you run this Jenkins pipeline, it will print the three messages in order during the build.
