💡 Hint

Common Mistakes

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

The sh step runs shell commands in Jenkins pipelines. Here, it runs the Maven build command.

Complete the code to trigger the pipeline on SCM changes using polling.

Spring Boot

pipeline {
    agent any
    triggers {
        [1] 'H/5 * * * *'
    }
}

💡 Hint

Common Mistakes

Using 'branchFilter' or 'whenBranch' are not valid Jenkins triggers.

The pollSCM trigger checks the source code management for changes using a cron schedule.

Fix the error in the Jenkins pipeline snippet to archive the build artifact 'target/app.jar'.

Spring Boot

post {
    success {
        [1] artifacts: 'target/app.jar'
    }
}

💡 Hint

Common Mistakes

Using 'archiveFiles' or 'saveArtifacts' causes pipeline errors.

The correct Jenkins step to save build outputs is archiveArtifacts.

4fill in blank

hard

Fill both blanks to define a stage that deploys the app only if the branch is 'main'.

Spring Boot

stage('Deploy') {
    when {
        [1] '[2]'
    }
    steps {
        echo 'Deploying application'
    }
}

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

💡 Hint

Common Mistakes

Using 'environment' or wrong branch names causes the stage to skip or error.

The when condition uses branch 'main' to run the stage only on the main branch.

5fill in blank

hard

Fill all three blanks to create a pipeline that builds, tests, and deploys with proper stages.

Spring Boot

pipeline {
    agent any
    stages {
        stage('Build') {
            steps {
                [1] 'mvn clean package'
            }
        }
        stage('Test') {
            steps {
                [2] 'mvn test'
            }
        }
        stage('Deploy') {
            steps {
                echo '[3]'
            }
        }
    }
}

💡 Hint

Common Mistakes

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

Not echoing a message in deploy stage misses feedback.

Use sh to run shell commands for build and test stages. The deploy stage echoes a message.
