Description

When running a JMH benchmark in IDEA from the raft module (e.g. SingleThreadExecutorBenchmark) the following error appears:

Exception in thread "main" java.lang.RuntimeException: ERROR: Unable to find the resource: /META-INF/BenchmarkList
	at org.openjdk.jmh.runner.AbstractResourceReader.getReaders(AbstractResourceReader.java:97)
	at org.openjdk.jmh.runner.BenchmarkList.find(BenchmarkList.java:103)
	at org.openjdk.jmh.runner.Runner.internalRun(Runner.java:256)
	at org.openjdk.jmh.runner.Runner.run(Runner.java:206)
	at org.apache.ignite.raft.jraft.util.concurrent.SingleThreadExecutorBenchmark.main(SingleThreadExecutorBenchmark.java:85)

Supposed cause

The maven-compiler-plugin in this module is configured to use a custom annotation processor which automatically disables other annotation processors, including the one from JMH. It should be manually enabled.
