> From a discussion on IRC, the Maven assembly speed is pretty bad, this is likely due to http://jira.codehaus.org/browse/MASSEMBLY-424 (process fork per dependency, ouch).
> Slimming the dependency tree will not only make the generated assembly more compact, it can speed up the build process.
> Will attach patch to propose slimming the dependencies based on stacks comments on the mailing list:
