NoClassDefFoundError caused by Kotlin readLine function

Question

Whenever i try to execute a .jar file containing my code, it throws NoClassDefFoundError: kotlin/io/ConsoleKt. So far i haven't found a solution to this problem but I think the problem has something to do with the readLine() function I have in the script but I don't know what. The weird thing is that my code ran perfectly in Intellij itself but once I built it started throwing this exception that never happened outside of IntelliJ. The specific error is:

Exception in thread "main" java.lang.NoClassDefFoundError: kotlin/io/ConsoleKt
        at com.quantumzizo.calcualtorkotlin.DisplayKt.main(Display.kt:23)
        at com.quantumzizo.calcualtorkotlin.DisplayKt.main(Display.kt)

Is there solution that can solve this?

Answer 1

So it turns out all I had to do was build a fat jar with all the dependencies. I used the Gradle plugin Shadow to make a fat jar. Props to @Endzeit for suggesting that I use it.
