jenkins Getting started with jenkins Installing Plugin from external source
Example
java -jar [Path to client JAR] -s [Server address] install-plugin [Plugin ID]
The client JAR must be the CLI JAR file, not the same JAR/WAR that runs Jenkins itself. Unique IDs can be found on a plugins respective page on the Jenkins CLI wiki (https://wiki.jenkins-ci.org/display/JENKINS/Plugins)
