Java 9 introduced modules. To depend on non-module code from modules, there are two options:

• JAR includes Automatic-Module-Name in its META-INF/MANIFEST.MF
• Name autogenerated from the filename

The latter is obviously not great because it can change at any time. Please add the Automatic-Module-Name entry to the JARs published from this project.
