Kotlin unresolved reference in IntelliJ

Question

I started off with the tutorial for learning Kotlin in IntelliJ.When I tried running the example i.e

fun main(args: Array) {
 prin         


        

Answer 1

For me, it was due to the project missing Gradle Libraries in its project structure.

Just add in build.gradle: apply plugin: 'idea'

And then run: $ gradle idea

After that gradle rebuilds dependencies libraries and the references are recognized!
