Detailed Description

Maven 4 is a new major version of Maven after 15 years of Maven 3. It brings many improvements, but also breaking changes.

Maven 4.0.0-rc-2 has been released in December 2024. Final 4.0.0 version is expected to be released in year 2025. In case the final version 4.0.0 is not released in time before Fedora Linux 43 change completion deadline, a release candidate version will be included in Fedora Linux 43 and may be updated to a newer version later in Fedora Linux 43 lifecycle.

The goal of this change is to package Maven 4 and make it available as alternative to Maven 3 in Fedora Linux 43.

It is not a goal to replace Maven 3, Maven 3 will continue to be available to users.

It is not a goal of this change to build Fedora packages with Maven 4 - XMvn, %mvn_build etc. will continue to use Maven 3. Switching Java packaging tools to use Maven 4 is planned in the future and a separate system-wide change proposal is expected be submitted for that effort, targeting a future Fedora Linux version newer than 43.

Benefit to Fedora

Java software developers will be able to use the latest version of the most popular Java development tool.

Fedora packagers will be able to start packaging Maven 4 plugins and extensions in preparation for switching Fedora packages to be built with Maven 4 by default in the future.
