Using the latest Gradle and .kts build scripts, how can I specify compiler options for a custom sourceSet? For example, for main and test sourceSets it's:

tasks {
    compileKotlin {
        kotlinOptions { ... }
    }
    compileTestKotlin {
        kotlinOptions {... }
    }
}

How would I specify options for some other buildSrc, let's call it "someOtherSrc"?

Don't think you can, seeing as custom sourceSets are virtual and don't have a direct kotlin target.

But have a look at your task graph. Kotlin plugin might be generating separate compile tasks, in which case you can access them via this:

tasks.named<KotlinCompile>("compileMyCustomSourceSetKotlin") { ... }

Thanks, it seems to be working! My custom sourceSets are for kotlinx.benchmark benchmarks, and there was a problem that benchmark code by default sing JVM 1.8 and my code uses JVM 16 as a target. Mixing of those two was problematic, now it looks like it's working...

Wow, I certainly did not expect this to work 😀

Btw, in the future always specify which kotlin plugin you're using for such questions - jvm, js or mpp

Sure thing! I'm not sure it's 100% working, there are still some kotlinx.benchmark errors... but at least I'm not getting the mismatched JVM version error

In the end, everything works perfectly! Thanks once again 😉
