XML : How to Assemble a Multi-Module Project with different jars in different folders in the main project root with the Maven Assembly plugin

I have a multi-module Apache Maven 3.3.3 project with n*** (multiple) modules:

  /mvnModular             /mainMod             /modules             /modules /module1             /modules /module2             /modules /module***             /modules /module***    

The idea is to have an application written in a way that a user will download the project mvnModular that only contains mainMod.jar in the mvnModular folder innitially. The mainMod folder has a jar file called mainMod.jar in /mvnModular/mainMod/target/ after mvn package, which is the main project. Then the project could be extended by adding modules to a folder called modules in the mvnModular root. Each of the modules has a module***.jar file in /mvnModular/module***/target after build, for example module1.jar.

How can I go about adding the .jar files in modules module1, module2, module3, module*** into a folder modules in the root, and mainMod.jar into the root folder, mvnModular?

.....

mainMod has only one file pom.xml:
