How to install a plugin in Jenkins manually
- Download the plugin.
- Inside Jenkins: Manage Jenkins → Manage Plugins → There is a tab called Advanced and on that page there is an option to upload a plugin (the extension of the file must be hpi).
Sometimes, when you download plugins you may get (.zip) files then just rename with (.hpi) and use the UI to install the plugin.
Yes, you can. Download the plugin (*.hpi file) and put it in the following directory:
<jenkinsHome>/plugins/
Afterwards you will need to restart Jenkins.
