It's a multi-project build. My "fat" jar contains all runtime dependencies,
including jars of 3 other projects. So assuming you have project dependencies
defined (i.e. compile project(":subproject")) that end up in the runtime
configuration (i.e. configurations.runtime), your subprojects will be included
in your "fat" jar using my previous example. This is one of the great things
about Gradle - makes it very easy to do this kind of thing.

Cool, thanks for the info!
Have you tried this on multi-project builds? or is this for single-projects
only
(not a deal breaker, just curious!)
