Question: somewhat related to Gradle - I'm currently configuring the Dokkatoo plugin, and want to add an external documentation link to the published Kotlin API reference.

dokkatoo {
  dokkatooSourceSets.configureEach {
    externalDocumentationLinks.register("gradle") {
      url("<https://docs.gradle.org/current/kotlin-dsl>")
    }
  }
}

It doesn't seem to be working as the plugin is saying that it can't find the

package-list

file. Is there some documentation I am missing?

It needs the

package-list

file to work properly. If you for example use

<https://kotlinlang.org/api/kotlinx.serialization/>

it would automatically find and use

<https://kotlinlang.org/api/kotlinx.serialization/package-list>

. But

<https://docs.gradle.org/current/kotlin-dsl/package-list>

does not exist, so either that URL is wrong or you need to additionally configure the package list url in your build script that belongs to that documentation.
