This document provides an introduction to Maven2, a project management and comprehension tool. It discusses why Maven2 is useful for managing dependencies and enforcing conventions. It also outlines how to set up a Maven2 project by defining the project object model (POM) file, and describes Maven2's lifecycle of goals like compiling, testing, packaging and deploying. Finally, it previews additional topics like customizing Maven2 projects, generating reports, using it for multi-module projects, and integrating with continuous integration tools.
