💡 Hint

Common Mistakes

Using a wrong library name that is not configured in Jenkins.

Forgetting to add the underscore (_) after the annotation.

The @Library annotation requires the exact name of the shared library to load, here 'utils'.

Complete the code to load multiple shared libraries 'utils' and 'helpers' in a Jenkins pipeline.

Jenkins

@Library(['[1]', 'helpers']) _
pipeline {
    agent any
    stages {
        stage('Test') {
            steps {
                echo 'Multiple libraries loaded'
            }

💡 Hint

Common Mistakes

Using parentheses instead of square brackets for multiple libraries.

Missing quotes around library names.

To load multiple libraries, list their names in an array. Here, 'utils' and 'helpers' are loaded.

Fix the error in the code to properly load the 'tools' shared library with a version '1.0'.

Jenkins

@Library('[1]@1.0') _
pipeline {
    agent any
    stages {
        stage('Build') {
            steps {
                echo 'Library version loaded'
            }
        }
    }
}

💡 Hint

Common Mistakes

Including the version in the blank causing '@1.0' to appear twice.

Using wrong separators like '-' or ':'.

The version is specified after '@' in the string. The blank should only contain the library name 'tools'.

Fill both blanks to load the 'common' library with version '2.1' and alias it as 'cmn'.

Jenkins

@Library('[1]@[2]') cmn
pipeline {
    agent any
    stages {
        stage('Deploy') {
            steps {
                script {
                    cmn.deployApp()
                }
            }
        }
    }
}

💡 Hint

Common Mistakes

Swapping version and name in blanks.

Using wrong version numbers.

The library name is 'common' and the version is '2.1' to match the alias usage.

Fill all three blanks to load libraries 'alpha', 'beta' version '3.0', and 'gammaLib'.

Jenkins

@Library(['[1]', 'beta@[2]', '[3]@1.5']) _
pipeline {

    stages {
        stage('Integration') {
            steps {
                script {
                    alpha.run()
                    beta.test()
                    gammaLib.deploy()
                }
