It is not possible to combine runnable JAR and classpath settings. It is possible to improve JMH to
accept classpath parameter, but the usual workflow is to make every library available via the build
system (whether it is Maven or Gradle) and shaded into the final benchmark. This also explains why
this is not a showstopper for most users.
