💡 Hint

Common Mistakes

Using 'run' instead of 'sh' causes an error.

Using 'execute' is not a Jenkins step.

In Jenkins pipelines, sh is used to run shell commands.

Complete the code to configure SCM polling with a cron schedule.

Jenkins

pipeline {
    agent any
    triggers {
        pollSCM('[1]')
    }
}

💡 Hint

Common Mistakes

Using 'main' or 'refs/heads/main' does not work; those are branch specifiers configured in SCM settings.

Cron schedules trigger polling regardless of branch; branch filters are set separately.

pollSCM requires a cron expression like H/5 * * * * to schedule SCM polling for changes.

hard

Fix the error in the Jenkinsfile to archive test results.

Jenkins

post {
    always {
        [1] artifacts: '**/test-results/*.xml', allowEmptyArchive: true
    }
}

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

AarchiveFiles

BarchiveArtifacts

Carchive

DsaveArtifacts

💡 Hint

Common Mistakes

Using 'archive' causes a syntax error.

Using 'saveArtifacts' is not a Jenkins step.

The correct Jenkins step to archive files is archiveArtifacts.

4fill in blank

hard

Fill both blanks to define a Jenkins pipeline with environment variables and a build step.

Jenkins

pipeline {
    agent any
    environment {
        APP_ENV = '[1]'
    }
    stages {
        stage('Build') {
            steps {
                [2] 'build.sh'
            }
        }
    }
}

💡 Hint

Common Mistakes

Using 'run' instead of 'sh' causes errors.

Setting APP_ENV to 'development' is valid but not the expected answer here.

Set APP_ENV to 'production' and use sh to run the build script.

5fill in blank

hard

Fill all three blanks to create a Jenkins pipeline that checks out code, runs tests, and archives results.

Jenkins

pipeline {
    agent any
    stages {
        stage('Checkout') {
            steps {
                [1] scm
            }
        }
        stage('Test') {
            steps {
                [2] 'runTests.sh'
            }
        }
    }
    post {
        always {
            [3] artifacts: '**/test-results/*.xml'
        }
    }
}

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

CarchiveArtifacts

Drun

💡 Hint

Common Mistakes

Using 'run' instead of 'sh' causes errors.

Using 'archive' instead of 'archiveArtifacts' causes errors.

Use checkout to get code, sh to run tests, and archiveArtifacts to save test results.
