Kotlin - IntelliJ Project Setup -


i want start new project kotlin jvm using intellij ide, can't configuration work. attempting follow this tutorial, , after didn't work (the "run '_defaultpackage'" option never showed up), started trying intuit supposed done without success. has happened far (repeatedly):

  • i created new project, selected "kotlin - jvm" project type.
  • i clicked "create..." button kotlin runtime on second page , selected "copy to: lib".
  • i click "finish" , project created has 1 module same name project. there no default source file or configuration.
  • i create kotlin file named "app.kt" (i've tried other names too, "main.kt"), , put following source code in:
fun main(args: array<string>){     println("hello world!") }
  • i right clicked on code editor , file in left pane find "run '_defaultpackage'" option mentioned in tutorial, failed find in either.
  • i create new kotlin configuration, asks put in "main class". seeing this, change code to:
public class main {     fun main(args: array<string>) {         println("hello world!")     } }
  • i edit configuration , set main class "main", , run configuration. fails error: "error running : function 'main' not found in class 'main'.

what missing?

a full answer how identify runnable class top-level main() function, or use main() method within class both documented in other stack overflow answer: how run kotlin classes

this covers running on command-line, within intellij (as question asks), gradle, , more.
