Wait no more, here comes Maven 4!
summary
Maven 4 (beta 4) arrives with concrete changes: existing Maven 3 projects still build but show new warnings and a new fail on severity flag to turn logged warnings into build failures; checksum verification of downloaded artifacts is enabled by default; resume-from now works reliably because the reactor keeps the original project graph; the pom splits into a mutable build pom and a generated consumer POM for deployment; Maven 4 requires Java 17 to run (toolchains let builds target older JDKs); BOM packaging and new pre/post lifecycle phases appear; performance is slightly worse today but test suite (~4,000 integrations) guards regressions.
