Release Notes – Maven 4.0.0-rc-2

Maven 4 release requires Java 17 for runtime.

This is release candidate release, is not suitable for production.

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.

The core release is independent of plugin releases. Further releases of plugins will be made separately. See the PluginList for more information.

Upgrading from Maven 3

Maven 4 brings a tons of changes. We've tried hard to maximise compatibility with Maven 3.x, but in order to have your build work with Maven 4, you will need to upgrade some plugins (such as maven-enforcer-plugin, maven-remote-resources-plugin, maven-shade-plugin, etc…) to their most recent versions.

If your build is leveraging Maven extensions, you may very well expect some breakage. Some extensions may need to be updated:

Contact the extensions' developers team to know their plans regarding supporting to Maven 4.

Known issues

  • the mvnenc tool used to encrypt passwords in settings is broken
