Automated management of Jenkins jobs via Maven. Much of the information needed by Jenkins when creating a job is already in the Maven pom. The SCM information and CI url are present there. Jenkins jobs also typically have names that reflect the groupId, artifactId, and version in some manner. This plugin automates the process of creating Jenkins jobs by harvesting information from the POM to create XML config files in the format Jenkins needs. The Jenkins CLI wrapper is then used to create, update, read, and delete Jenkins jobs on the CI server.

There is a newer version: 1.2.8
