The .jpi and .hpi files are just zip files (JPI = jenkins plug in, HPI = hudson plug in). If you put .hpi in your plugins directory (possibly / var / lib / jenkins / plugins) and restart Jenkins, it will install the plug-in.
I found that Jenkins-ci.org stores .hpi files, and installing this method leaves them as .hpi files. Installation through gui changes them to .jpi.
You can also look at one of the existing puppet modules for Jenkins.
