Excluding aggregating project from SBT jar assembly production

Question

How can one exclude an aggregating project that does nothing but aggregating subproject from producing a jar file ?

Answer 1

You must disable the plugin for the aggregating project:

aggregatorProject.disablePlugins(AssemblyPlugin)

This will however disable the plugin for the aggregator and the aggregated projects.

You can enable the plugin for the aggregated projects by enabling them explicitly:

aggregatedProject.enablePlugins(AssemblyPlugin)
