I’m currently trying out the new EAP for Kotlin 1.3.50. I wanted to use the new Duration in my project but keep getting the following compile error. I am unable to reproduce it in a new project when using Duration. Can anyone see what’s wrong?

This is the code what causes the error in my project:

import kotlin.time.Duration
class DurationExample {
    var duration: Duration? = null
}

If I put this in a new project it works fine.

Did you annotate the class/file with @UseExperimental(ExperimentalTime::class)?

[Thomas]

@Sergey Chelombitko I used the compiler argument. That made the experimental warning disappear

[Thomas]

I tried adding the annotation as well but still the same compile error

Try disabling kapt

I've reproduced it in plain java class and filed as https://youtrack.jetbrains.com/issue/KT-33157

Great, thank you Ilya!
