> It is said "To view all options run jmh with the -h flag." in
> https://github.com/apache/kafka/blob/trunk/jmh-benchmarks/README.md. But it
> doesn't work with the following error:
> /jmh.sh -h running gradlew :jmh-benchmarks:clean :jmh-benchmarks:shadowJar in
> quiet mode If this is not your first run and there is nothing changed, you
> can skip this build stage by ./jmh.sh skip-build ... Building project 'core'
