How to run benchmarks?

[vdvman1]

I'm planning on doing some experiments with improving the performance (and maybe the functionality) of brigadier.
I have forked the repository, cloned it to my local machine, and imported the gradle project into IntelliJ IDEA.
All the tests are running successfully, but I can't seem to figure out how to get the benchmarks to run. There does not seem to be any gradle tasks for running the benchmarks, and I have not been able to get the JMH plugin for IntelliJ IDEA to run the benchmarks.
Are there any instructions on how to run the benchmarks? And if not, could someone please explain and/or link me to some resources on getting the benchmarks to work?
Everything I have been able to find either requires a maven project (which this repo does not seem to contain), or would require changes to the gradle project. I would prefer not to have to change the build process if I can avoid it
