Multi project distribution

Hi! I’m trying to make a dist of a multi project build. The root project looks something like this:

apply plugin: 'distribution'
version 1.0
distributions {
    main {
        baseName = 'someName'
        contents {
            from 'nodes'
      into 'nodes'

It just copies a folder with some files to the dist.

I now want each subproject to inject its stuff into the dist. I want to add each subprojects jar, any dependecies, and possibly some other files etc…

I have no idea how to inject from the subproject to the root. Should I even do something like that? What i mean is something like this:

subprojects {
   apply java...
     // pseudocode
   jack into the root project dist plugin
   put my produced jars and dependencies in a folder with my name
