Practice - 5 Tasks

1fill in blank

easy

Complete the code to enable lightweight checkout in a Jenkins pipeline.

Jenkins

checkout([$class: 'GitSCM', branches: [[name: '*/main']], doGenerateSubmoduleConfigurations: false, extensions: [[1]], userRemoteConfigs: [[url: 'https://github.com/example/repo.git']]])

Drag options to blanks, or click blank then click option'

A[$class: 'CloneOption', shallow: true]

B[$class: 'CloneOption', noTags: true]

C[$class: 'CleanBeforeCheckout']

D[$class: 'LocalBranch']

💡 Hint

Common Mistakes

Using 'noTags: true' does not enable lightweight checkout.

Using 'CleanBeforeCheckout' cleans workspace but does not affect checkout depth.

The CloneOption with shallow: true enables lightweight checkout by cloning only the latest commit.

medium

Complete the code to enable lightweight checkout in a Jenkins declarative pipeline.

Jenkins

pipeline {
  agent any
  options {
    [1]
  }
  stages {
    stage('Checkout') {
      steps {
        checkout scm
      }
    }
  }
}

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using 'skipDefaultCheckout()' disables checkout entirely.

Timeout and concurrency options do not affect checkout behavior.

The lightweightCheckout() option enables lightweight checkout in declarative pipelines.

hard

Fix the error in the Jenkins pipeline snippet to correctly enable lightweight checkout.

Jenkins

pipeline {
  agent any
  options {
    [1]
  }
  stages {
    stage('Build') {
      steps {
        checkout([$class: 'GitSCM', branches: [[name: '*/develop']], extensions: [], userRemoteConfigs: [[url: 'https://github.com/example/repo.git']]])
      }
    }
  }
}

💡 Hint

Common Mistakes

Using 'skipDefaultCheckout()' disables checkout, causing errors.

Using 'cleanBeforeCheckout()' cleans workspace but does not enable lightweight checkout.

Adding lightweightCheckout() in the options block enables lightweight checkout properly.

4fill in blank

hard

Fill both blanks to configure lightweight checkout with shallow clone and no tags in a scripted pipeline.

Jenkins

checkout([$class: 'GitSCM', branches: [[name: '*/master']], extensions: [[1], [2]], userRemoteConfigs: [[url: 'https://github.com/example/repo.git']]])

Drag options to blanks, or click blank then click option'

A[$class: 'CloneOption', shallow: true]

B[$class: 'CleanBeforeCheckout']

C[$class: 'CloneOption', noTags: true]

D[$class: 'LocalBranch']

Attempts:

3 left

💡 Hint

Common Mistakes

Using 'CleanBeforeCheckout' does not affect clone depth or tags.

Using 'LocalBranch' is unrelated to lightweight checkout.

Using CloneOption with shallow: true enables shallow clone, and noTags: true avoids fetching tags, both helping lightweight checkout.

5fill in blank

hard

Fill all three blanks to create a Jenkins pipeline snippet that uses lightweight checkout with shallow clone, no tags, and disables submodule configurations.

Jenkins

checkout([$class: 'GitSCM', branches: [[name: '*/feature']], doGenerateSubmoduleConfigurations: [1], extensions: [[2], [3]], userRemoteConfigs: [[url: 'https://github.com/example/repo.git']]])

Drag options to blanks, or click blank then click option'

Afalse

B[$class: 'CloneOption', shallow: true]

C[$class: 'CloneOption', noTags: true]

Dtrue

Attempts:

3 left

💡 Hint

Common Mistakes

Setting doGenerateSubmoduleConfigurations to true enables submodules, which is not lightweight.

Using only one CloneOption misses part of the lightweight checkout setup.

Setting doGenerateSubmoduleConfigurations to false disables submodule configs. Using CloneOption with shallow: true and noTags: true enables lightweight checkout.
