Hello, I am a bit confused by intellij warnings in gradle file. in particular, we have

kotlin {
  jvmToolchain {
    languageVersion.set(JavaLanguageVersion.of(17))
  }
  sourceSets.all {
    languageSettings {
      progressiveMode = true
    }
  }
}

tasks.withType(org.jetbrains.kotlin.gradle.tasks.KotlinCompile).configureEach {
  kotlinOptions {
    jvmTarget = JavaVersion.VERSION_17 //see: <https://youtrack.jetbrains.com/issue/IDEA-252328>
    freeCompilerArgs = ["-Xjsr305=strict", "-Xemit-jvm-type-annotations", "-opt-in=kotlin.RequiresOptIn"]
  }
}

with kotlin 1.8 and groovy build file. sourceSets.all is suggested to be replaced with source.configureEach, which seems to work but it deviates from kotlin docs: https://kotlinlang.org/docs/multiplatform-dsl-reference.html#language-settings. moreover, using configureEach leads to languageSettings generating a warning as method call is ambiguous . what is the best approach here?

second confusing (or better, I am not sure what to do) warning is the deprecation of `kotlinOptions`: idea still does not fully support language version, as per https://youtrack.jetbrains.com/issue/IDEA-252328, but the suggested solution requires replacing toolchain with unfortunately no improvements were made yet. The sourceCompatibility and targetCompatibility are safe options for now. source and target compatibility, and toolchain are mutually exclusive, hence the use of kotlinOptions. I am mostly concern about upgrading to gradle 8, probably kotlin options will go then, is there another option?

General rule that you should always prefer lazy configuration configureEach instead of all
(but not sure about what is the issue with languageSettings, in general all/configureEach should be the same

[thanksforallthefish]

with all intellij warns of No candidates found for method call languageSettings., in the end it’s just intellij but was looking for an option that would make ide happy too

[thanksforallthefish]

I should probably migrate to kotlin gradle file, I think ide support is a bit better there

[gildor]

Honestly with Groovy it never works for me in IDE, it’s essentially useless, works as text editor

While editing a Groovy DSL build script in the IDE, that's exactly the one case where the -all distribution is helpful to improve developer life, but really only while editing the file.

But yeah, Kotlin DSL does not only have "a bit" better IDE support, but amazingly better IDE support. :-)

Also upgrading Gradle has nothing to do with your problem, Kotlin Options are from the Kotlin Gradle plugin so independent from Gradle version.

And regarding the kotlinOptions, as far as I remember you should use something like

compilerOptions.jvmTarget = org.jetbrains.kotlin.gradle.dsl.JvmTarget.JVM_17

instead

ah, fair point, thanks for the explanation
