A modern programming language that makes developers happier.

kotlinlang

Well there's probably an equivalent syntax for that :simple_smile:

```
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 :stuck_out_tongue:

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

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

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.

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() {
```

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

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