Hi. How can I write the following in build.gradle.kts?

sourceSets {
    main {
        java { srcDir "./src" }
        kotlin { srcDir "./src" }
        resources { srcDir "./resources" }
    }
    test {
        kotlin { srcDir "./test" }
    }
}

Maybe this will help

[Dmitry Kandalov]

Unfortunately, no. Because java.sourceSets["main"].kotlin doesn't exist (probably needs some extension function import).

[irus]

java {
  (sourceSets) {
    "main" {
      withConvention(KotlinSourceSet::class) {
        kotlin.srcDirs("wherever")
      }
    }
  }
}

[Dmitry Kandalov]

yes, just noticed

[Dmitry Kandalov]

thank you! 👍

[Dmitry Kandalov]

(can't say that I'm impressed by the new syntax though)

[irus]

Yep, I think there are better option exists.

[Dmitry Kandalov]

In case somebody wants to know exact answer to the question:

java.sourceSets {
    "main" {
        java.srcDirs("./src")
        kotlin().srcDirs("./src")
        resources.srcDirs("./resources")
    }
    "test" {
        kotlin().srcDirs("./test")
    }
}
fun Any.kotlin() = withConvention(KotlinSourceSet::class) { kotlin }

[gildor]

Yes, because convention is legacy way to extend Gradle, there is a plan to deprecate them, but many plugins still use them, and not sure that there is an easy replacement,l for some cases. Problem that conventions are very dynamic, so hard to use them in Kotlin but very flexible, you can extend everything. Maybe this sourceset configuration should be moved to dsl of Kotlin plugin

[gildor]

BTW you can convert fun `Any.kotlin() `to val Any.kotlin and replace Any with actual target (not sure about class tho)

[Dmitry Kandalov]

yes, this works val Any.kotlin: SourceDirectorySet get() = withConvention(KotlinSourceSet::class) { kotlin }
even though there is also fun Project.kotlin(configure: KotlinProjectExtension.() -> Unit): Unit = ... in org.gradle.kotlin.dsl

[Dmitry Kandalov]

(might keep it as a function for now so that it's more noticeable... on the other hand there are four things within the script called kotlin anyway, val won't make anything more confusing)
