Description

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' with Scala version 2.12.11 Building project 'streams-scala' with Scala version 2.12.11 gradle build done running JMH with args [-h] Exception in thread "main" java.lang.NoSuchMethodError: joptsimple.OptionDescriptor.options()Ljava/util/Collection; at org.openjdk.jmh.runner.options.OptionFormatter.lineFor(OptionFormatter.java:62) at org.openjdk.jmh.runner.options.OptionFormatter.format(OptionFormatter.java:51) at joptsimple.OptionParser.printHelpOn(OptionParser.java:342) at joptsimple.OptionParser.printHelpOn(OptionParser.java:328) at org.openjdk.jmh.runner.options.CommandLineOptions.showHelp(CommandLineOptions.java:457) at org.openjdk.jmh.Main.main(Main.java:46) JMH benchmarks done

The different version of
jopt used in KAFKA and JMH is the root cause. KAFKA uses jopt 5.0.4 while
JMH uses jopt 4.6. You can get the jopt change logs from http://jopt-simple.github.io/jopt-simple/changes.html
