Summary:  Modern software projects are no longer solely monolithic creations of single local project teams. With the increased availability of robust, enterprise-grade open source components, today's software projects require dynamic collaboration among project teams and often depend on a mix of globally created and maintained components. Now in its second generation, the Apache Maven build system -- unlike legacy build tools created before the Internet-enabled era of global software development -- was designed from the ground up to take on these modern challenges. This tutorial gets you started with Maven 2.
