All you need to know about Maven 4!
summary
Maven 4 requires Java 17 to run while still compiling older target JDKs, and removes the old Plexus resolver; the plugin API is redesigned so unmaintained custom plugins can break. It introduces a generated consumer POM (model 4.0) and optional build POM (4.1), adds automatic versioning for parent and inter-module dependencies, uses a project-local repository to avoid polluting ~/.m2, improves reactor ordering and lifecycle with before/after phases, and supports alternate syntaxes via an SPI extension.
