Yoann Rodière at first sight it seems that it is not possible with ModiTect generate a module-info.java descriptor using Java 8.
In fact, according to the `README.md` file:

Note that moduleInfoSource and moduleInfoFile can be used on Java 8, allowing to add a Java 9 module descriptor to your JAR also if you did not move to Java 9 for your own build yet. moduleInfo can only be used on Java 9 or later.

At this point I think we have to switch to to JDK11 for our build, but maybe still using ModiTect to generate module-info.java descriptors. What you think about?
