SBT aggregating subproject

Given a project structure:

rootProject
  aggregatingSubProject
    subA
    subB
  subC

How do I run the package task for aggregatingSubProject and all its aggregated projects, without specifying them by hand?

So far I can only have subA and subB built when doing package in the rootProject - regardless if I put .aggregate(subA, subB) in aggregatingProject's build.sbt.

I need the rootProject to define common settings for the build and I want to build multiple projects (some aggregating other projects, like aggregatingSubProject does) in a single build.

EDIT: I need to do this without specifying all the sub-sub-projects in the root build.sbt. I'd like to define subA and subB in aggregatingSubProject/build.sbt.

Using sbt 0.13.16.

Given this in build.sbt:

val rootProject = project in file(".")
val aggregatingSubProject = project
val subC = project

and this in aggregatingSubProject/build.sbt:

aggregateProjects(subA, subB)

val subA = project
val subB = project

You can run aggregatingSubProject/package and get:
