Builds 10x Faster with Turbo Reactor
summary
A custom Builder extension called Maven Turbo Builder changes Maven’s reactor to publish a module after its package phase so downstream modules start earlier, cutting real-build bottlenecks on a 2 million line, 2 million lines, 1000 modules monolith where a full mvn clean verify drops from ~41 minutes to ~21 with -T and then gains another ~30% average speedup with Turbo; with build cache enabled similar projects fall from ~20 minutes to ~2. Observability uses the Velocity extension; watch for test-jar deps and integration-test port conflicts.
