@Shawn Thanks! I meant, I already specify Java version (or so it seems) in` java` block, how can I not define it in tasks?

[gildor]

java block is for java code, Kotlin is for Kotlin class files

[Krotick]

Thank you! So, if I do not use Java directly, is it safe to remove java block completely?

Do you happen to know if there is a similar directive for Kotlin, e.g.

kotlin {
  jvmTarget = 1.8
}

[gildor]

Nope, it's not exposed as gradle extension, only as task, so have to configure Kotlin compiler tasks (by default there are 2 of them: compileKotlin and compileTestKotlin, but your snippet configure all Kotlin compile tasks applying config by task type

[gildor]

Also agree that it should be exposed as extension, always forget to report this proposal to issue tracker

[Krotick]

So, should my build.gradle.kts have something like that:

val javaVersion = JavaVersion.VERSION_1_8.toString()
val kotlinVersion = KotlinVersion(1, 31).toString()

tasks.withType<KotlinCompile> {
  sourceCompatibility = javaVersion
  targetCompatibility = javaVersion

  kotlinOptions {
    jvmTarget = javaVersion
    apiVersion =kotlinVersion
    languageVersion = kotlinVersion
  }
}

[Krotick]

Or I can do this but it seems extremely verbose:

val compileKotlin: KotlinCompile by tasks
val compileTestKotlin: KotlinCompile by tasks

compileKotlin.sourceCompatibility = javaVersion
compileKotlin.targetCompatibility = javaVersion
compileTestKotlin.sourceCompatibility = javaVersion
compileTestKotlin.targetCompatibility = javaVersion

compileKotlin.kotlinOptions {
  jvmTarget = javaVersion
  apiVersion = kotlinVersion
  languageVersion = kotlinVersion
}

compileTestKotlin.kotlinOptions {
  jvmTarget = javaVersion
  apiVersion = kotlinVersion
  languageVersion = kotlinVersion
}

[gildor]

Exactly, so withType approach is the best what you have

[Krotick]

gotcha. thank you!
