easy

Complete the code to delete all files in the Jenkins workspace.

Jenkins

steps.sh 'rm -rf [1]/*'

💡 Hint

Common Mistakes

Using a hardcoded path instead of the workspace variable.

Using a relative path that may not point to the workspace.

The environment variable ${WORKSPACE} points to the current Jenkins job workspace directory. Using it ensures the cleanup targets the correct folder.

medium

Complete the Jenkins pipeline step to clean the workspace before starting the build.

Jenkins

pipeline {
  agent any
  stages {
    stage('Cleanup') {
      steps {
        [1]()
      }
    }
  }
}

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

💡 Hint

Common Mistakes

Using shell commands directly instead of the pipeline step.

Using deleteDir() which deletes the current directory but may not clean all workspace files.

The cleanWs() step is a Jenkins Pipeline utility that cleans the current workspace safely.

Fix the error in the shell command to clean the workspace safely.

Jenkins

sh 'rm -rf [1]'

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

D/tmp/*

💡 Hint

Common Mistakes

Deleting the workspace folder itself causing Jenkins to fail.

Using incorrect or hardcoded paths.

Using ${WORKSPACE}/* deletes all files inside the workspace but keeps the workspace directory itself intact, preventing errors.

4fill in blank

hard

Fill both blanks to create a post-build step that cleans the workspace only if the build fails.

Jenkins

post {
  failure {
    steps {
      [1]()
      sh 'rm -rf [2]/*'
    }
  }
}

💡 Hint

Common Mistakes

Using deleteDir() which may delete the workspace folder itself.

Using hardcoded paths instead of ${WORKSPACE}.

The cleanWs() step cleans the workspace safely. Using ${WORKSPACE} ensures the shell command targets the correct directory.

5fill in blank

hard

Fill all three blanks to define a pipeline that cleans workspace before and after the build.

Jenkins

pipeline {
  agent any
  stages {
    stage('Cleanup') {
      steps {
        [1]()
      }
    }
    stage('Build') {
      steps {
        echo 'Building...'
      }
    }
  }
  post {
    always {
      [2]()
      sh 'rm -rf [3]/*'
    }
  }
}

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

💡 Hint

Common Mistakes

Using different cleanup steps inconsistently.

Using hardcoded paths instead of environment variables.

Using cleanWs() in the cleanup stage and post steps ensures workspace is cleaned before and after the build. The ${WORKSPACE} variable targets the correct directory in the shell command.
