Hello, IntelliJ doesn't allow me to run fun main() {} without the args array (works with it), why is that?

[Shawn]

how old is your Kotlin plugin?

[Marcin Wisniowski]

1.3.41-release-IJ2018.2-1

[Shawn]

that looks more than recent enough lol

[Shawn]

Oh, do you have the correct language version set in your Project Structure?

[Marcin Wisniowski]

I only see a setting for Java version, not Kotlin version.

[Shawn]

If you click on Modules in the sidebar, you’ll see a project tree

[Shawn]

under wherever your main package lives, you should see a Kotlin entry in the tree

[Shawn]

should look something like this

Looks like this to me

[Shawn]

Hm, it kinda looks like Kotlin isn’t set up for your project 😕

[Shawn]

did you use like a gradle starter or something like that?

[Marcin Wisniowski]

But it definitely works, so how is that possible 🤔

[Shawn]

Honestly have no idea

[Shawn]

if you’re using gradle, maybe try reimporting the project

[Shawn]

if not, I suppose you could hit the + button and add the Kotlin module manually

[Marcin Wisniowski]

Oh I added a Kotlin module to that tree and switches the language version there, now it works! Thank you.
