Practice - 5 Tasks

1fill in blank

easy

Complete the code to checkout the current branch in Jenkins pipeline.

Jenkins

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

💡 Hint

Common Mistakes

Hardcoding branch name instead of using environment variable.

Using incorrect variable names.

Using env.BRANCH_NAME dynamically checks out the current branch in Jenkins pipeline.

2fill in blank

medium

Complete the code to select the Jenkinsfile path based on the branch name.

Jenkins

def jenkinsfilePath = (env.BRANCH_NAME == 'main') ? '[1]' : 'Jenkinsfile.dev'

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

💡 Hint

Common Mistakes

Using incorrect Jenkinsfile names.

Confusing branch names with Jenkinsfile names.

The default Jenkinsfile is usually named Jenkinsfile. For the main branch, we use this path.

3fill in blank

hard

Fix the error in the pipeline script to load the correct Jenkinsfile per branch.

Jenkins

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

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

💡 Hint

Common Mistakes

Using dot notation inside string interpolation incorrectly.

Using underscores or dots instead of dash.

The Jenkinsfile path should be constructed with a dash before the branch name, like Jenkinsfile-feature.

4fill in blank

hard

Fill both blanks to define a pipeline that loads a Jenkinsfile based on the branch name and runs it.

Jenkins

def file = 'Jenkinsfile[1][2]'
load file

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

💡 Hint

Common Mistakes

Using underscore instead of dash.

Using undefined variable names.

The Jenkinsfile name is constructed by joining 'Jenkinsfile', a dash, and the branch name from env.BRANCH_NAME.

5fill in blank

hard

Fill all three blanks to create a Jenkins pipeline that checks out the current branch, selects the Jenkinsfile path, and loads it.

Jenkins

pipeline {
  agent any
  stages {
    stage('Checkout') {
      steps {
        checkout([$class: 'GitSCM', branches: [[name: '[1]']], userRemoteConfigs: [[url: 'https://github.com/example/repo.git']]])
      }
    }
    stage('Load Jenkinsfile') {
      steps {
        def file = '[2][3]'
        load file
      }
    }
  }
}

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

Denv.BRANCH

💡 Hint

Common Mistakes

Using incorrect environment variable names.

Not matching branch name in checkout and Jenkinsfile path.

The pipeline checks out the current branch using env.BRANCH_NAME, then constructs the Jenkinsfile path by joining 'Jenkinsfile-' and the branch name from env.BRANCH_NAME.
