Continuous integration is a software development practice where developers regularly merge their code changes into a central repository, after which automated builds and tests are run.
Jenkins is a continuous integration suite that checks your code out of a repository, builds and packages it, and dumps it out to a server so you can test it-all hands-off. It can use Maven or Ant as its build tool. In summary, Jenkins can use Maven as its build tool for continuous integration.
