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

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 the troubleshooting section

[John O'Reilly]

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/

[John O'Reilly]

That needs to be applied in target project?

[tapchicoma]

yep

[tapchicoma]

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

[John O'Reilly]

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
