The Maven team has gone to the ends of the earth to ensure backward compatibility, improve usability, increase performance, allow safe embedding, and pave the way for implement many highly demanded features. This talk will briefly cover the process and tooling changes that have occurred in the Maven project in order to accomplish what we have done with Maven 3.0, as well as discuss the architectural and feature changes. Some of the process changes include setting up a multi-platform Hudson grid, building out a framework of over 440 integration tests, creating integration tests for all core Maven plugins, and systematically seeking out Maven 2.x OSS projects to validate Maven 3.x’s compatibility. We also built out a framework that measures disk I/O, network I/O, memory consumption, and CPU utilization to ensure that performance doesn’t degrade.
