Maven is a tool for building Java applications. It has a pom.xml file that contains all the build instructions as well as a list of project dependencies. The pom.xml file has a bewildering amount of configurable options. The complete Maven pom.xml structure documentation (project descriptor file) is here on the Maven web site. This page contains all the elements and descriptions.
