What's the location of a file? Isn't it in a source root?

It is in root of the project

It says that it's a source root at the same time

Not sure I understood

Try clicking on this cross

Magic! It worked

If it's part of the module sources then kotlin-main-kts should be present in this module's dependencies. It was not your case. If it's outside of the source roots, separate module is created for this script, kotlin-main-kts is added to it automatically based on file extension

Strange not my case, at least I don’t see extra module in project settings. Unless you say it is some invisible module. Let me check iml file or .idea folder

By the way, if you're interested in Kotlin scripting, Kotlin Notebook plugin might be also interesting for you https://plugins.jetbrains.com/plugin/16340-kotlin-notebook

Thank you! I saw it on the KotlinConf, I didn’t expect it is available already

You've created a project with the source root same as the project root. Why it happened - it's another question

Oke, doesn’t matter much! It kinda works now
