What is the practical use of JPMS layers?

[Christian Stein]

An exemplary use of module layers is documented and implemented here:
https://github.com/moditect/layrry

Copied from its "Why Layrry?" section:

This is where Layrry comes in: utilizing the notion of module layers, it
> provides a declarative approach as well as an API for assembling
> modularized applications, organized in module layers. The JARs to be
> included are described using Maven GAV (group id, artifact id, version)
> coordinates, solving the issue of retrieving all required JARs in the right
> version.



Module layers allow to use different versions of one and the same module in
> different layers of an application (as long as they are not exposed in a
> conflicting way on module API boundaries).


Cheers,
Christian
