In its current implementation, the modulepath is entirely inferred from the module-info.java's required modules (and their transitive dependencies, in m2e 1.9/Photon). m2e ignores Java 9 options from the maven-compiler-plugin configuration section.
I suggest you create a sample project, try it Photon's latest CI build[1], to see where we're at, and open a bug report[2], attaching that project.
