I'm working on writing some benchmarks in Okio for a PR. Any idea why ./gradlew jmh is only running writeHex benchmarks? This is my first time dipping my toes in JMH so any help is appreciated 😬

Commenting out the writeHex benchmark results in the following error.

> Task :okio:jvm:jmh:jmh FAILED
Caching disabled for task ':okio:jvm:jmh:jmh' because:
  Build cache is disabled
Task ':okio:jvm:jmh:jmh' is not up-to-date because:
  Task has not declared any outputs despite executing actions.
:okio:jvm:jmh:jmh (Thread[Execution worker for ':',5,main]) completed. Took 0.53 secs.

After some research, looks like this is the culprit

jmh {
  jvmArgs = ['-Djmh.separateClasspathJAR=true']
  include = ['com\\.squareup\\.okio\\.benchmarks\\.WriteHexadecimalBenchmark.*']
  duplicateClassesStrategy = 'warn'
}

yup, changing it did the job.
