Java 11 unnamed module issue when using Maven model

So, I'm trying to migrate a tool from Java 8 to Java 11.
I did the first step to make it work without modules and the code compiles successfully.

Now I'm trying to add the module-info.java, and I first faced issues because of the libraries used in my tool. Some are already compatible with Java 11 (e.g. Lombok) but some others are not, so I'm trying to import them using the requires and the artifactId name.
But I seem stuck because of my Maven model & Maven model builder dependency as I get the following error when building:

[ERROR] the unnamed module reads package org.apache.maven.model.merge from both maven.model.builder and maven.model
[ERROR] module maven.model.builder reads package org.apache.maven.model.merge from both maven.model.builder and maven.model
[ERROR] module maven.model reads package org.apache.maven.model.merge from both maven.model.builder and maven.model

What should I do for this kind of error? It seems I need both (build still fails if I comment one or the other). Does it mean I cannot add modules to my tool because of my dependencies?
N.B.: The libraries are set to their latest version (i.e. 3.6.3)

I "fixed" this using the maven-exec-plugin as described in the answer to this question.

Edit: When running the main class through the maven-exec-plugin, the compiler does (for some reason unknown to me) not complain anymore about the conflicts.
