When you build with Maven on a multicore / multi-CPU machine, it would often be possible to build different subprojects in parallel. Is there a way to do this with Maven? Is there a plugin for this / whatever?
Maven 3 (as of beta 1) now supports parallel builds as an experimental feature.
For example,
mvn -T 4 clean install # Builds with four threads
mvn -T 1C clean install # One thread per CPU core
mvn -T 1.5C clean install # 1.5 thread per CPU core
Full documentation can be found on the Maven wiki: Parallel builds in Maven 3 - Apache Maven - Apache Software Foundation.
