10 Things You Need to Know about the Maven 3 Toolset

Maven 3 is out the door now and developers everywhere are beginning the migrations to this exciting new version of the most popular build tool on the planet. This talk assumes a basic knowledge of Maven 2 and will equip you with all the practical and technical details necessary for you and your team to migrate to Maven 3. We'll explore the performance improvements, features that make debugging Maven issues easier, and changes to POMs that may require modifications to your build, but will result in more determinate build outputs.

Maven 3.0 has undergone major refactorings, and correspondingly, a battery of backwards compatibility tests to ensure a smooth transition from Maven 2.0. These refactorings prepare Maven for the next several years of development, including the separation of the POM file language from from the POM in-memory processor, which is already leading to Groovy, Ruby and YAML based POM file parsers. While Maven 3 is designed as a drop in replacement, the tips and tricks in this presentation will make your migration smooth and let you extract the greatest performance benefit from this ground-up reimplementation while simultaneously minimizing your POM editing efforts.
