Generating jar for JavaFX project in Kotlin

While I was playing around with Kotlin I wondered if I can generat a jar for a JavaFX app written in Kotlin. So I wrote a simple app and it worked on IntelliJ IDEA, but when I decided to generate the jar it never worked! It says that it can't find or load the main class.

I guess the problem is that when it asked for the main class in the project settings I entered the application class name (which doesn't contain the main method, as it has to be at the package level) while in pure Java I could just put the main method inside the application class and it would work perfectly. So how should I get around this?

EDIT: just tried changing the target from JavaFX Application to a normal Jar and it worked. Don't know why it's not working with the JavaFX Application target.

If you have your main function defined in package named foo.bar:

package foo.bar

fun main(args: Array<String>) {
   // ...
}

Then, your main class is foo.bar.BarPackage - it is generated by Kotlin compiler to hold top-level functions of the package
