What is difference between Maven and Jenkins?
Maven is a build tool that handles dependencies and the life cycle of a software. It also has a plug-in design that allows you to add additional tasks to the standard compile/test/package/install/deploy tasks, whereas Jenkins is a continuous integration suite that verifies your code out of a repository, builds and bundles it, and unloads it out to a server for testing.
To conclude, Jenkins can use Maven as its continuous integration build tool. If you do not want to employ Jenkins, you can use Maven instead.
