Can't build when used with Kotlin experimental features

[ShreckYe]

The library I am benchmarking uses Kotlin's ExperimentalUnsignedTypes. I have already added

@OptIn(ExperimentalUnsignedTypes::class)

to the benchmark class and

tasks.withType<KotlinCompile>().configureEach {
    kotlinOptions.freeCompilerArgs += "-Xopt-in=kotlin.RequiresOptIn"
}

to build.gradle.kts but still got the following Gradle error:

Execution failed for task ':app:mainBenchmarkGenerate'.
> There was a failure while executing work items
   > A failure occurred while executing kotlinx.benchmark.gradle.JmhBytecodeGeneratorWorker
      > Generation of JMH bytecode failed with 1errors:
          - Group name should be the legal Java identifier.
           [org.openjdk.jmh.generators.reflection.RFMethodInfo@3212c77c]

* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output. Run with --scan to get full insights.

Hi @ShreckYe,
The problem may come with quoted benchmark function names with spaces.
Could you please check if that is the case for you?

Thanks. I checked the code again and found the reason. It's actually due to using a single expression function with = as a @Benchmark function, and the inferred return type is not Unit. It just happened that I used experimental features inside so I made a mistake there. Sorry for this.

Created a separate issue for documenting the supported return types: #219
