Go to “Manage Jenkins” –> “Manage Plugins” –> “Available” Tab –> Search for “GitHub plugin” and install it.

Go to “Manage Jenkins” –> “Configure System” –> Locate “Github” section and “Add Github Server”.

API URL – If you server is github.com, your “API URL” would be “https://api.github.com” Otherwise if you use GitHub Enterprise, specify its API endpoint here (e.g., https://ghe.acme.com/api/v3/).

Credentials – You can create your own personal access token in your account GitHub settings.

Token should be registered with scopes: Refer https://github.com/settings/tokens/new.

Add credentials (your Github token), Apply and “Test Connection”.

a) Check the GitHub project checkbox and set the Project URL to point to your GitHub Repository

b) Under Source Code Management, check Git and set the Repository URL to point to your GitHub Repository

c) Under Build Triggers, check the “Build when a change is pushed to GitHub” checkbox

a) From your GitHub repository, go to Settings and then to Integrations & Services

b) Click on Add Service and add ‘Jenkins (GitHub plugin)’

c) Set the Jenkins hook URL as the URL for your Jenkins machine, and add /github-webhook/

Actually if you do the web hook settings from Jenkins -> Github plugin configuration (mentioned above), you will still see webhooks get created in github. So , above two approaches basically doing the same thing.

I personally like it to create webhook from Github, because in this way you don’t have to share or store github user info in jenkins.

Steps : 1. Login into Github (with Admin) 2. Go to the repository you want to hook with jenkins 3. Click on settings tab -> webhooks & services 4. Click on Add Webhook 5. Enter payload url : like : http://:8080/github-webhook/ 6. Select content type as json 7. you are done

Now you do the changes and commit , you will see jenkins build get trigger automatically. Don’t forget to do the settings in jenkins jobs to start the build when push code in github.
