kotlinlang

Hey all. I'm trying to have a mixed java/kotlin project, but I keep getting `"error: cannot find symbol"` messages.

I followed what was outlined here: <https://kotlinlang.org/docs/mixing-java-kotlin-intellij.html|https://kotlinlang.org/docs/mixing-java-kotlin-intellij.html>, specifically the steps:

&gt; You can also open the Kotlin runtime configuration manually from *Tools* | *Kotlin* | *Configure Kotlin in Project*.
&gt; 
Here is a minimal project to showcase the issue:

Kotlin value classes are effectively invisible to and unusable by Java code

in your code,
```@JvmInline
value class PositiveInt(private val value: @Positive Int)```
does not create a class with a constructor that can be called by Java. there are box methods, but those aren't accessible either <https://youtrack.jetbrains.com/issue/KT-50518>
