Jar file only works with Java classes but not with Kotlin


You got some “extracted…” files there which I don’t have. What I’ve found out is that if I delete these 2 files and add the KotlinJavaRuntime from the right instead, I get the same error. So how did you get the “extracted” files there?!

Edit: Now I found out how to get these files there, but I don’t have such a lib-folder, so where is it from? How can I get it? And why does it only work with these extracted .jars and not the KotlinJavaRuntime?!
