Is

java {
   toolchain { .. }
}

a replacement for this

tasks.withType(JavaCompile).configureEach { task ->
        task.sourceCompatibility = JavaVersion.VERSION_17
        task.targetCompatibility = JavaVersion.VERSION_17
    }

and this

tasks.withType(org.jetbrains.kotlin.gradle.tasks.KotlinCompile).configureEach { task ->
        task.kotlinOptions {
            jvmTarget = "17"

?

You can replace

tasks.withType(JavaCompile).configureEach { task ->
        task.sourceCompatibility = JavaVersion.VERSION_17
        task.targetCompatibility = JavaVersion.VERSION_17
    }

with

java {
    toolchain {
        languageVersion.set(JavaLanguageVersion.of(17))
    }
}

how about kotlin?

[mudasar187]

just change java to kotlin if you are using Gradle Kotlin DSL

[ursus]

unfortunately not .. just wondering, is that single declaration then supposed to work for all modules & both java and kotlin?

[CLOVIS]

It's intended to work only for the current module, for both Java and Kotlin

[ursus]

just to be sure -- kotlin bytecode target will be set with the java { .. } syntax, correct?

will it work for android module as well? the sample I posted works only for pure java modules
