For example, the build lifecycle (you also have the clean and site lifecycles which are different) is composed of the following phases: validate : validate the project is correct and all necessary information is available. In order to use Maven from command line, you need to have it installed as a standalone application.

By default, the goals search for tasks that would run if the user invoked mvn deploy. To include multiple phases in the search, use the buildplan.
