I have a build.gradle.kts

[karelpeeters]

Well there's probably an equivalent syntax for that simple smile

[Robert]

val compileTestKotlin: KotlinCompile by tasks

compileTestKotlin.kotlinOptions.jvmTarget = "1.8"
compileTestKotlin.kotlinOptions.jvmTarget = "1.8"

val compileKotlin: KotlinCompile by tasks

compileKotlin.kotlinOptions.jvmTarget = "1.8"

val compileJava: JavaCompile by tasks

compileJava.targetCompatibility = "1.8"
compileJava.sourceCompatibility = "1.8"

val compileTestJava: JavaCompile by tasks

compileTestJava.targetCompatibility = "1.8"
compileTestJava.sourceCompatibility = "1.8"

Should probably work 😛

[karelpeeters]

Ah right, I don't know what the issue is then.

[Robert]

I mean I just added all that, though it didnt fix my problem 😞

Does it change if you use the Gradle test runner in "Preferences | Build, Execution, Deployment | Build Tools | Gradle | Runner"? Do you have a Kotlin MPP project or a regular project? It also may be an IDEA bug, something like <https://youtrack.jetbrains.com/issues/IDEA?q=%22requires%20target%20release%22%20-Resolved%20>, but I haven't looked into it.

[Robert]

Yes, it says No tasks available after clicking the green triangle. But it is also because I mixed kotlin.test.* and io.kotlintest.*. Which am I supposed to use?

class MyTest {
    @kotlin.test.Test
    fun testThis() {

[Robert]

I have now checked delegate IDE build/run actions to gradle

[Robert]

And select Platform test runner. Then one level up called Gradle I configured Delegate settings to Default

[Robert]

I'll test some more combinations.
