After installing Jenkins, you'll need to install a plug-in needed to perform build validation.
To install the required Jenkins plug-in
- If you are not already displaying the Jenkins dashboard in a browser, navigate to the Jenkins URL (for example, http://localhost:8080, if working on the Jenkins host computer), and then log in as the administrator user you created during installation.
- On the sidebar menu, click Manage Jenkins.
- In the System Configuration section, click Manage Plugins.
- Click the Available tab, and then enter the keyword Post in the search box to filter the plug-in list.
- Scroll down and select the PostBuildScript plug-in. This plug-in allows you to execute custom scripts after a build is complete; you'll use this plug-in later to perform build validation operations.
- At the bottom of the window, click Download now and install after restart. Jenkins automatically downloads and installs the plug-in.
- In the Installing Plugins/Upgrades pane, select Restart Jenkins when installation is complete and no jobs are running.
After Jenkins completes the restart, you are ready to configure Jenkins.
