r/Kotlin on Reddit: Is IntelliJ the only working IDE for Kotlin?
January 20, 2022 -
I tried NetBeans, and discovered that its Kotlin plugin has been abandoned for years. Then I tried Eclipse, and it did not work at all. I used the latest Eclipse and installed the Kotlin plugin using the in-built software installation feature, but creating a new Kotlin project threw an exception, and manually creating a .kt file also threw an exception. So, unless you are those kind of geniuses who can write code using Notepad, you are pretty much vendor-locked in IntelliJ?

I know there are Kotlin plugins for Visual Studio Code. How well they work may be another story, though. Since JetBrains created the language, odds are their IDEs are going to be the most well supported for it.

Whatever problem IntelliJ is giving you will be much easier to fix than the problems of an alternate IDE.

Even in 2019.1.3 that error is there .
A solution that always works for me is :
Build menu => Rebuild Project
Tested with JDK 12.0.1
That should be fixed though by IntelliJ team as soon as possible as more and more Java projects are passing to JDK 11 ++

I had the same problem. I worked in a pure Java project managed with Maven. Till some days ago I applied the solution "rebuild" the project, but sometimes the error came back again.
After more investigation, I found that after disable "Enable migration detection" menu, the problem disappears.
I hope this helps.

Configuring Kotlin Support | IntelliJ Platform Plugin SDK
Existing Java classes can be converted to their Kotlin equivalents by using the J2K converter (part of the Kotlin plugin). In addition to null safety, type-safe builders, and Kotlin Coroutines the Kotlin language offers many convenient features for plugin development, which make plugins easier to read and simpler to maintain. Much like Kotlin for Android, the IntelliJ Platform makes extensive use of callbacks, which are straightforward to express as lambdas in Kotlin.
