The Jenkins project started life as in 2004, but the user and developer community decided to rename the project to Jenkins in early 2011 after asserted trademark claims to the name Hudson (see for questions related to the previous name).

Jenkins lets you automate many tasks, such as compilation, tests and deployments. Jobs can be scheduled using cron-like scheduling, or using triggers, such as whenever a source code repository is updated.

Jenkins is Java-based and recent versions require Java 7 (or later) on the master. The Jenkins master can manage multiple build nodes (slaves). Jobs can be run across multiple machines in order to perform jobs in parallel, distribute load, or build and test cross-platform software. Capacity can be easily added — Jenkins can automatically set up a new build slave on any SSH-accessible machine; it can even launch new machines to run jobs on, e.g. via cloud-computing or virtualisation plugins.

Jenkins supports a long list of plugins in a wide variety of categories to support different source control systems, run specialised build tools, send notifications, provide build reports and analytics, customise build workflows, etc. Many are hosted as open source under the Jenkins organisation on GitHub.

Jenkins is an open-source project with an enhanced enterprise product managed by CloudBees. The open source software is hosted on GitHub and distributed under the MIT license. There is an active development community with public documentation, getting started tutorials and a wiki. A new version is released approximately once a week, with more stable "long-term support" releases roughly every 12 weeks.

With its 10th anniversary Jenkins 2.0 was released in April 2016 and has some enormous changes:

  • Pipeline support out of the box
  • Better UI experience with dynamic pages
  • More plugins are bundled to prevent the paradox of choice

With version 2.0 the weekly release plan was reintroduced.
