A modern programming language that makes developers happier.

kotlinlang

I'm trying to run benchmarks project mentioned in <https://blog.jetbrains.com/kotlin/2024/04/k2-compiler-performance-benchmarks-and-how-to-measure-them-on-your-projects/> with a couple of KMP samples I have but running in to errors e.g.

```* What went wrong:
An exception occurred applying plugin request [id: 'org.jetbrains.kotlin.android']
> Failed to apply plugin 'org.jetbrains.kotlin.android'.
   > Unknown output type: JSON```

and likes of

```org.gradle.tooling.BuildException: Could not execute build using connection to Gradle installation '/Users/johnoreilly/dev/github/k2-performance-metrics/build/benchmarkRuns/gradle-user-home/wrapper/dists/gradle-8.4-bin/1w5dpkrfk8irigvoxmyhowfim/gradle-8.4'.
	at org.gradle.tooling.internal.consumer.ExceptionTransformer.transform(ExceptionTransformer.java:51)
	at org.gradle.tooling.internal.consumer.ExceptionTransformer.transform(ExceptionTransformer.java:29)```

I've tried with <https://github.com/joreilly/Confetti> and <https://github.com/joreilly/PeopleInSpace> so far

you need to apply "org.jetbrains.kotlin.jvm" as well in `buildSrc` - see last paragraph in <https://github.com/Kotlin/k2-performance-metrics?tab=readme-ov-file#troubleshooting|the troubleshooting section>

ah, ok, thanks...I'll try that.  I had just been following instructions at <https://blog.jetbrains.com/kotlin/2024/04/k2-compiler-performance-benchmarks-and-how-to-measure-them-on-your-projects/>

That needs to be applied in target project?

and target project should allow to change kotlin version via `kotlin_version` Gradle property

hmm, still getting that error for some reason.  I'll try and grab some time again and have another go in case I missed something
