Jenkins Popular Build Triggers Automate the CICD Pipeline

Introduction:

Jenkins build triggers allow for the automation of builds and deployments based on specific events or conditions. With Jenkins build triggers, you can initiate builds when changes are made to a repository, on a schedule, or when triggered by external factors like webhook notifications.

Benefits of using Jenkins build triggers include improved efficiency and productivity through automated build processes, faster feedback loops for developers, the ability to integrate with various tools and services, and the flexibility to customize build triggering based on specific requirements.

Some Popular Triggers:
