JMX Config Tool CLI is not packaged correctly

The bin folder of opennms contains a script called jmx-config-generator. It's a /bin/sh script starting, some how, a opennms_jmx_config_generator.jar. That jar is not a jar with dependencies and will just respond with a java.lang.NoClassDefFoundError.
After an assembly of the entire opennms a jmx-config-tool with all dependencies is located in:
./opennms-assemblies/jmx-config-generator-onejar/target/org.opennms.assemblies.jmx-config-generator-onejar-1.13.0-SNAPSHOT.one-jar.jar
