Can I make maven-assembly-plugin go faster?

I have a maven multi-module project. The final goal wraps up all the libraries, etc., that we build in a tarball and RPM for distribution. This goal uses the maven-assembly-plugin, and it takes forever -- usually a quarter to a half of our total build time.

I think we're already telling Maven to run multithreaded (though I'm not positive, and don't know how to check). Is there any other optimization I can do to make unpacking / repacking go faster? Is it just a matter of using a beefier machine? Our project doesn't seem that big (end result is ~70-80 MB) but it takes well over a minute just for that one phase.

Upgrade to the latest version of the Maven Assembly plugin. Newer versions are much faster than older ones.

I've seen this happen when the maven reactor is huge, for a multi-module, multilevel project with enormous dependency hierarchy. If this is the your case, you might consider splitting your maven project to smaller ones, or suggest/ask for improvement for the maven assembly-plugin.

Try increasing memory by specifying MAVEN_OPTS=-Xmx[some large value]. I managed to speed it up significantly, but it is still slower than tar. If I have time I will get the sources and profile it.
