my biggest concern with Maven 4 is not JDK runtime requirement, but plugins future when a plugin wants to be able to use the new Maven 4 API IIUC, Maven 4 has a compatibility layer to run Maven Plugin 3.x (= built with Maven 3 plugin API). On our core plugins, there is a Maven 4 branch that tests what the plugin would become when it migrates to new Maven 4 API (and check that Maven 4 API works as expected) But IIUC, once a plugin uses Maven 4 API, it de-facto cannot be run on Maven 3 Questions: - is that true at plugin level or goal level? - new Maven 4 API for now is not so much about providing new features, but improving/clarifying plugin expectations from Maven core: are there known features in Maven 4 API not available in Maven 3 that would bring stronger interest in writing a goal for Maven 4? concern: does it mean that we either should not upgrade our master branches to Maven 4 API too early? Will we need to maintain a 3.x branch in parallel to 4/ main branch? And the questions I have for plugins maintained at Maven project level will impact every third party plugin maintainer: we need to make things explicit, IMHO The JVM upgrade in parallel IMHO is less a concern, as it is a consequence of previous plugin prerequisite choice on Maven Hervé > > Guillaume > > Le sam. 20 janv. 2024 à 19:18, Martin Desruisseaux > > <martin.desruisse...@geomatys.com> a écrit : > > Hello > > > > I would like a little clarification about the Java version for Maven 4. > > I saw debate on this mailing list, but has a decision been reached?
