🔄 How to Set Up a Poll SCM Pipeline in Jenkins | Automatically Trigger Builds on Code Changes In this practical Jenkins tutorial, we walk you through how to configure Poll SCM (Source Code Management) in a Jenkins Pipeline, allowing your Jenkins job to automatically check for code changes in your repository at regular intervals—and trigger builds only when changes are detected. If you're not using webhooks, or if your repository host doesn’t support them, Poll SCM is the perfect way to keep your CI/CD pipeline responsive and up-to-date with the latest code changes. 🎯 What You’ll Learn in This Video: ✅ What Poll SCM is and how it works in Jenkins ✅ How to configure Poll SCM in Jenkins Freestyle and Pipeline jobs ✅ Writing pollSCM triggers in a Jenkins Declarative Pipeline ✅ Cron syntax for polling schedules (e.g. every 5 minutes, hourly, etc.) ✅ Tips to avoid excessive polling or missed changes ✅ Debugging tips when your builds aren’t triggering as expected 🛠 Complete Setup Demonstrated: Connecting your Jenkins job to a GitHub/Git repository Writing the triggers { pollSCM('H/5 * * * *') } block inside a Jenkinsfile Viewing SCM polling logs to confirm the polling mechanism Triggering the build only when code changes are detected Performance considerations when using Poll SCM 📌 Common Use Cases: CI builds without webhook support Lightweight polling when webhook reliability is an issue Secure environments where outgoing webhooks are blocked 📘 Helpful Resources: Jenkins Poll SCM Docs: https://www.jenkins.io/doc/book/pipel...
