Who: The Apache Software Foundation (ASF): all-volunteer developers, stewards, and incubators of nearly 150 Open Source projects and initiatives.
What: In development for nearly 10 years, and an ASF Top-Level Project since 2003, Apache Maven is the build system of choice for millions of developers and thousands of organizations world-wide.
Why: Maven 3 represents the culmination of nearly two years of work re-architecting the internals of the system based on experience gained over the last five years with Maven 2.x. Maven 3 is faster, more reliable, and more extensible, with users already reporting 10-40% improvements in build time over Maven 2.
"A key priority for our users was backward compatibility," said Brian Fox, Vice President of Apache Maven. "We've invested a significant amount of time and effort to ensure a smooth transition while maintaining backward compatibility with Maven 2 builds and plugins."
Highlights of the release include:
- Parallel build capability
- Conversion of IoC system from Plexus to Guice, including a Plexus compatibility layer
- Rewritten dependency resolution logic, designed to be extensible and embedded in other applications
- Improved POM validation during the build to warn users of potential problems
- Improved error handling and messages
- Decoupled reporting engine from the core
- New inheritance and interpolation code designed to be extensible and allow composition of POMs in future releases
- More robust handling of local repository data
- True plugin classpath isolation
- Massively improved regression test suite for Maven core and plugins
