Hi!

For my java projects I can write the following in my Gradle file:

java.targetCompatibility = JavaVersion.1_8

Is there a similar way I can set the jvmTarget for my Kotlin code?

[Chris Lee]

kotlin {
   jvmTarget.value = JavaVersion.1_8
}

[Tianyu Zhu]

@Chris Lee I can't seem to find the jvmTarget field...

[Chris Lee]

apologies, that was for Kotlin Gradle DSL; this is for straight-up Kotlin:

tasks.withType<KotlinCompile>().configureEach {
    kotlinOptions {
        jvmTarget = "1.8"
    }
}

[ephemient]

if you use the Kotlin extension instead

kotlin {
    target {
        compilations.all {
            kotlinOptions.jvmTarget = "1.8"

you will only have to change target to targets.all when moving to Kotlin Multiplatform

Better to use Gradle JVM toolchain feature that works both for Java and Kotlin: https://kotl.in/gradle/jvm/toolchain

[tapchicoma]

it as well configures `jvmTarget`/`targetCompatibility`

[Tianyu Zhu]

@tapchicoma It seems like I can just write

kotlin.jvmToolchain(8)

Is that right?

[tapchicoma]

Yes, this shortcut was added in 1.7.20 release

[tapchicoma]

already existing configuration approach is still there if you need more specific toolchain configuration
