(Ctrl+Alt+Shift+I) and type Hardcoded Strings: only find the hardcoded strings in the .java files and not find strings in .kt files
Ah, well actually there's an update. Kotlin IDE does understand org.jetbrains.annotations.PropertyKey 11, but it does not always work. I have had problems if the bundle contains more than one language.
Example:
fun message(@PropertyKey(resourceBundle = "Messages") id: String) =
ResourceBundle.getBundle("Messages").getString(sid) ?: "###$id###"
