while migrating to kotlin 2.0.0 i got this error on this line of code

jvm("desktop") {
    jvmToolchain(17)
}

Using 'jvmToolchain(Int): Unit' is an error. Configuring JVM toolchain in the Kotlin target level DSL is prohibited. JVM toolchain feature should be configured in the extension scope as it affects all JVM targets (JVM, Android).

As the error message said, move it one line (scope) up.

it got deprecated better use this instead

jvm("desktop") {
    compilerOptions {
        apiVersion.set(org.jetbrains.kotlin.gradle.dsl.KotlinVersion.KOTLIN_2_0)
    }
}

The language version is unrelated.

This is the correct way to set the JVM toolchain:

kotlin {
  jvmToolchain(17)
  jvm("desktop")
}
