Kotlin: Unresolved reference: ofInstant

Question

I am new to Kotlin and I am trying to compile an open source code, that is written in Kotlin. The build using gradle is failing with error:

Unresolved reference: ofInstant

This is the line that is causing the error:

package common.time
import java.time.*
private val UTC = ZoneId.of("UTC")
fun Instant.toUtcLocalDate() = LocalDate.ofInstant(this, UTC)

I have the latest JDK installed. Any help is appreciated. Thanks

Answer 1

LocalDate.ofInstant() is only in Java 9 and later. You can use ZonedDateTime.ofInstant(this, UTC).toLocalDate() instead.
