💡 Hint

Common Mistakes

Using '15 * * * *' triggers only at minute 15 every hour.

The cron expression */15 * * * * triggers the job every 15 minutes.

medium

Complete the code to trigger a Jenkins job on GitHub push events.

Jenkins

pipeline {
  triggers {
    [1]()
  }
  stages {
    stage('Test') {
      steps {
        echo 'Testing...'
      }
    }
  }
}

Using pollSCM instead of githubPush.

The githubPush() trigger responds to GitHub push events.

Fix the error in the triggers block to poll SCM every 10 minutes.

Jenkins

pipeline {
  triggers {
    pollSCM('[1]')
  }
  stages {
    stage('Deploy') {
      steps {
        echo 'Deploying...'
      }
    }
  }
}

B*/5 * * * *

C10 * * * *

D0 10 * * *

💡 Hint

Common Mistakes

Using '*/10 * * * *' can cause all jobs to poll simultaneously.

The expression H/10 * * * * polls SCM every 10 minutes with a hashed start time.

hard

Fill both blanks to trigger a Jenkins job every day at midnight and on SCM changes.

Jenkins

pipeline {
  triggers {
    cron('[1]')
    [2]('H/5 * * * *')
  }
  stages {
    stage('Build') {
      steps {
        echo 'Building...'
      }
    }
  }
}

💡 Hint

Common Mistakes

Using githubPush instead of pollSCM for SCM polling.

The cron('0 0 * * *') triggers daily at midnight, and pollSCM('H/5 * * * *') polls SCM every 5 minutes.

5fill in blank

hard

Fill all three blanks to trigger a Jenkins job every hour, on GitHub push, and every Sunday at 2 AM.

Jenkins

pipeline {
  triggers {
    cron('[1]')
    [2]()
    cron('[3]')
  }
  stages {
    stage('Test') {
      steps {
        echo 'Testing...'
      }
    }
  }
}

Attempts:

💡 Hint

Common Mistakes

Using pollSCM instead of githubPush for GitHub push.

The first cron('0 * * * *') triggers hourly, githubPush() responds to GitHub push events, and the second cron('0 2 * * 0') triggers every Sunday at 2 AM.
