The GitHub plugin for Jenkins is the most basic plugin for integrating Jenkins with GitHub projects. If you are a GitHub user, this plugin enables you to:<\/div>\n
 <\/div>\n
    \n
  • Schedule your build<\/li>\n
  • Pull your code and data files from your GitHub repository to your Jenkins machine<\/li>\n
  • Automatically trigger each build on the Jenkins server, after each Commit on your Git repository<\/li>\n<\/ul>\n
    This saves you time and lets you incorporate your project into the Continuous Integration (CI) process.<\/span><\/div>\n

    Step 1 – Install the Github Jenkins plugin<\/h4>\n\n\n\n

    Go to “Manage Jenkins” –> “Manage Plugins” –> “Available” Tab –> Search for “GitHub plugin” and install it.<\/p>\n\n\n\n

    Step 2 – Configure the “GitHub plugin” with github accounts and taken<\/h4>\n\n\n\n

    Go to “Manage Jenkins” –> “Configure System” –> Locate “Github” section and “Add Github Server” and do following modification.<\/p>\n\n\n\n

    • 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\/).<\/li>
    • 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) and Apply. <\/li>
    • “Test Connection”.<\/li><\/ul>\n\n\n\n

      Step 3 – Configure Jenkins Job on which you want push trigger should be effective.<\/h4>\n\n\n\n
      • Check the GitHub project checkbox and set the Project URL to point to your GitHub Repository<\/li>
      • Under Source Code Management, check Git and set the Repository URL to point to your GitHub Repository<\/li>
      • Under Build Triggers, check the “GitHub hook trigger for GITScm polling” checkbox<\/li><\/ul>\n\n\n\n

        \"\"<\/figure>\n\n\n\n

        Step 4 – Configure “webhook” on github for the specific repository.<\/h4>\n\n\n\n

        Go to repostory settings and then “Webhooks” and Click on “Add Webhook” and then fill a “Payload URL” and leave secret empty. “Payload URL” must be your jenkins server url postfix with “\/github-webhook\/”. Such as http:\/\/35.154.114.196:8080\/github-webhook\/<\/p>\n\n\n\n

        Step 5 – Commit and push in Git repo using workstation and verify the job triggered new build or not?<\/h4>\n\n\n\n
