A modern programming language that makes developers happier.

kotlinlang

how do you set
```sourceCompatibility = 8
targetCompatibility = 8```
if you use `jvm { withJava() }` ?

i just use this:
```configure&lt;JavaPluginConvention&gt; {
    sourceCompatibility = JavaVersion.VERSION_1_8
}```


I use:
```    jvm {
        compilations.all {
            kotlinOptions.jvmTarget = "1.8"```
It corresponds to `targetCompatibility` . I don't think `sourceCompatibility ` has any meaning with respect to kotlin source (assuming you don't write native Java).

Thanks, I have Java files, so I am going to try out christoph's solution. I am already using jvmTarget for Kotlin
