Maven 3.0.4

The Apache Maven team would like to announce the release of Maven 3.0.4.

Maven 3.0.4 is available for download.

Maven is a software project management and comprehension tool. Based on the concept of a project object model (POM), Maven can manage a project's build, reporting and documentation from a central place.

Maven 3 aims to ensure backward compatibility with Maven 2, improve usability, increase performance, allow safe embedding, and pave the way to implement many highly demanded features.

NOTE: Maven 3.0.4 has a new default Http Wagon based on Apache HttpClient 4.1.2. You must read various available settings documented here.

Some enhancements are now included by default:

  • http(s) connection pool.
  • default preemptive authentication support.
  • a default read timeout configured to 30 minutes.

The core release is independent of the plugins available. Further releases of plugins will be made separately. See the Plugin List for more information.

We hope you enjoy using Maven! If you have any questions, please consult:
