💼 Career

Knowing how to configure Jenkins email notifications is a common task for DevOps engineers and CI/CD pipeline maintainers.

1

Create basic Jenkins pipeline script

Create a Jenkins pipeline script with a pipeline block and a stage named 'Build' that just echoes 'Building project...'.

Jenkins

pipeline {
    agent any
    stages {
        stage('Build') {
            steps {
                // Your code here
            }
        }
    }
}

Need a hint?

Use pipeline and stage blocks. Inside steps, use echo to print the message.

2

Add recipient email configuration

Add a variable called recipientEmail at the top of the script and set it to '[e-mail]'.

Jenkins

def recipientEmail = '[e-mail]'

pipeline {
    agent any
    stages {
        stage('Build') {
            steps {
                echo 'Building project...'
            }
        }
    }
}

// Your code here

Need a hint?

Define recipientEmail before the pipeline block.

3

Add email notification step

Inside the 'Build' stage steps, add an emailext step that sends an email to recipientEmail with subject 'Build Status' and body 'The build has completed.'.

Jenkins

def recipientEmail = '[e-mail]'

pipeline {
    agent any
    stages {
        stage('Build') {
            steps {
                echo 'Building project...'
                // Your code here
            }
        }
    }
}

Need a hint?

Use the emailext step with named parameters to, subject, and body.

4

Print confirmation after email sent

After the emailext step inside the 'Build' stage steps, add a echo statement that prints 'Email notification sent.'.

Jenkins

def recipientEmail = '[e-mail]'

pipeline {
    agent any
    stages {
        stage('Build') {
            steps {
                echo 'Building project...'
                emailext(
                    to: recipientEmail,
                    subject: 'Build Status',
                    body: 'The build has completed.'
                )
                // Your code here
            }
        }
    }
}

Need a hint?

Use echo 'Email notification sent.' after the emailext step.
