What’s New in Maven 4? Model Upgrade, Flattened POMs, and Parallel Builds
Maven 4, released at the end of 2025, introduces a 4.1.0 POM model, separates build and consumer POMs to flatten dependencies, adds explicit classpath‑jar and module‑jar artifact types, renames modules to subprojects, and implements a tree‑based lifecycle for true parallel builds, all while remaining backward compatible.
