Jenkins

pipeline {

💡 Hint

Common Mistakes

Using 'clean install' when only compilation is needed.

Using 'test' which runs tests but does not compile separately.

The compile goal compiles the source code of the project. It is a common first step in Maven builds.

2fill in blank

medium

Complete the code to run a Gradle build task in a Jenkins pipeline.

Jenkins

pipeline {
  agent any
  stages {
    stage('Build') {
      steps {
        sh './gradlew [1]'
      }
    }
  }
}

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

Aassemble

Bbuild

Cclean

Dtest

💡 Hint

Common Mistakes

Using 'assemble' which only packages without running tests.

Using 'clean' which deletes build files but does not build.

The build task compiles, tests, and assembles the project in Gradle.

3fill in blank

hard

Fix the error in the npm build command in this Jenkins pipeline.

Jenkins

pipeline {
  agent any
  stages {
    stage('Build') {
      steps {
        sh 'npm [1]'
      }
    }
  }
}

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

Abuild

Crun build

Dstart

💡 Hint

Common Mistakes

Using 'npm build' which is not a valid npm command.

Using 'npm start' which runs the start script, not build.

To run a custom npm script like 'build', you use npm run build. Just 'npm build' is not a valid command.

4fill in blank

hard

Fill both blanks to run a Maven clean and package in a Jenkins pipeline.

Jenkins

pipeline {
  agent any
  stages {
    stage('Build') {
      steps {
        sh 'mvn [1] [2]'
      }
    }
  }
}

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

Cpackage

Dtest

💡 Hint

Common Mistakes

Using 'install' instead of 'package' which also installs to local repo.

Using 'test' which only runs tests.

The clean goal removes previous build files, and package compiles and packages the project.

5fill in blank

hard

Fill all three blanks to run a Gradle clean, build, and test in a Jenkins pipeline.

Jenkins

pipeline {
  agent any
  stages {
    stage('Build and Test') {
      steps {
        sh './gradlew [1] [2] [3]'
      }
    }
  }
}

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

Bbuild

Ctest

Dassemble

Attempts:

💡 Hint

Common Mistakes

Using 'assemble' instead of 'build' which does not run tests.

Omitting 'clean' which may cause stale files.

The commands clean, build, and test run cleaning, building, and testing respectively in Gradle.
