Expected behaviour
No exception is thrown.
To Reproduce
I tracked it down to our expect/actual typealias for WeakReference on iOS:
Common:
public expect class WeakReference<T: Any>(referred: T) {
public fun get(): T?
}iOS Implementation:
import kotlin.native.ref.WeakReference
internal actual typealias WeakReference<T> = WeakReference<T>It seems that Dokka gets confused by the WeakReference<T> = WeakReference<T> part and ends up in infinite recursion. The following workaround fixes the problem:
internal actual typealias WeakReference<T> = kotlin.native.ref.WeakReference<T>Dokka configuration
Just running ./gradlew dokkaHtml
Installation
- Operating system: macOS
- Build tool: Gradle v7.2
- Dokka version: 1.6.0, also reproduced with current master (1.6.10-SNAPSHOT)
Are you willing to provide a PR?
Possibly - need a hint where to start though.
