Hello here. I have updated my Kotlin to 1.6.0 and when compiling some Kotlin code I get a warning and I don't know how to solve it.

In your

build.gradle.kts

file you have entered Kotlin version 1.4.0

@Ayfri I am not using Gradle for this project. Just the IntelliJ IDEA build system.

Then it should be in the project settings

@Ayfri, I checked the project settings, and even reconfigured Kotlin for the project, to no avail.

Same here

Show your Kotlin configuration of your projet in the project settings

Oh @Ayfri, BTW, for such types of projects, you can't see the Kotlin version in the project settings.

Maybe "File | Settings | Build, Execution, Deployment | Compiler | Kotlin Compiler"?

Thanks @Alexey Belkov [JB], that worked! Thanks a lot!🙏🏼
