module-version and modules-hash) by the jar command line tool (using
Unfortunately, neither the ModuleInfoExtender itself nor the used asm-lib is
exported to allow external use. Is it planned to change this in the final
release of Java 9?

manipulated to create a jar file. Having to re-implement this functionality in
3rd party tools (like Ant, Maven, Gradle, etc.) doesn’t make it better ;-)
