summary

Maven Wrapper now in Apache generates mavenw scripts that download a specific distribution (demo used 3.8.5) so clones build without preinstalled Maven; Maven Wrapper now in Apache. A new build/consumer POM separation in Maven 4 snapshots lets the deployed POM differ from the VCS POM (demo: removed parent version — Maven 3 fails the schema, Maven 4 snapshot builds and installs with the version reinserted). Reactor fixes enable resume/resume-from across sibling modules (no mvn install needed; dotmvn root marker) and large projects (hundreds of modules). Maven Daemon (mavend) keeps JVM/plugins hot, groups parallel logs, and cuts cold scala-plugin runs from ~5s to ~2s; it currently uses Maven 3.8.3 and has plugin/thread-safety and Apple Silicon caveats.
