1fill in blank

easy

Complete the code to define a Jenkins pipeline with two SCM repositories.

Jenkins

pipeline {
  agent any
  stages {
    stage('Checkout') {
      steps {
        [1] [
          $class: 'GitSCM',
          branches: [[name: '**']],
          userRemoteConfigs: [[url: 'https://github.com/example/repo1.git']]
        ]
      }
    }

💡 Hint

Common Mistakes

Using 'build' or 'run' instead of 'checkout' will cause errors.

The checkout step is used to pull source code from SCM repositories in Jenkins pipelines.

Complete the code to add a second SCM repository checkout in the same stage.

Jenkins

pipeline {
  agent any
  stages {
    stage('Checkout') {
      steps {
        checkout scm
        [1] [
          $class: 'GitSCM',
          branches: [[name: '**']],
          userRemoteConfigs: [[url: 'https://github.com/example/repo2.git']]
        ]
      }
    }
  }
}

💡 Hint

Common Mistakes

Using other step names like 'build' will not work.

To checkout multiple repositories, use the checkout step multiple times with different SCM configurations.

hard

Fix the error in the code to correctly checkout two repositories in parallel.

Jenkins

pipeline {
  agent any
  stages {
    stage('Checkout') {
      steps {
        parallel {
          repo1: {
            [1] [
              $class: 'GitSCM',
              branches: [[name: '**']],
              userRemoteConfigs: [[url: 'https://github.com/example/repo1.git']]
            ]
          },
          repo2: {
            [1] [
              $class: 'GitSCM',
              branches: [[name: '**']],
              userRemoteConfigs: [[url: 'https://github.com/example/repo2.git']]
            ]
          }
        }
      }
    }
  }
}

💡 Hint

Common Mistakes

Using different step names causes syntax errors.

In Jenkins pipelines, the checkout step is used to pull code. Using it inside parallel allows simultaneous checkouts.

Fill both blanks to define two SCM repositories with different branches.

Jenkins

pipeline {
  agent any
  stages {
    stage('Checkout') {
      steps {
        checkout scm: [
          $class: 'GitSCM',
          branches: [[name: '[1]']],
          userRemoteConfigs: [[url: 'https://github.com/example/repo1.git']]
        ]
        checkout scm: [
          $class: 'GitSCM',
          branches: [[name: '[2]']],
          userRemoteConfigs: [[url: 'https://github.com/example/repo2.git']]
        ]
      }
    }
  }
}

💡 Hint

Common Mistakes

Using branch names without 'refs/heads/' prefix causes errors.

The branches field specifies which branch to checkout. Common branches are main and develop.

hard

Fill all three blanks to create a map of repository names to their URLs and branches.

Jenkins

def repos = [
  '[1]': [url: 'https://github.com/example/repo1.git', branch: '[2]'],
  '[3]': [url: 'https://github.com/example/repo2.git', branch: 'refs/heads/develop']
]

💡 Hint

Common Mistakes

Mixing up repo names or missing the branch prefix.

This map links repository names to their URLs and branches. The first repo is 'repo1' on 'main' branch, the second is 'repo2'.
