In Li Haoyi's recent talk he shows how incredibly fast Java compiler is. Also demonstrates how much overhead comes from Maven and Gradle. If Java build feels sluggish, know that first 50s is lost due to maven. Mill still has rough edges. The project is evolving fast and things change, but it is a great tool. The BSP support in IDEs is IMO still work in progress (not related to Mill itself) so for JVM languages, Maven and Gradle still have a leg up.
