2.0.0-Beta: Illegal use of flexible type deserializer.

[colinrtwhite]

Describe the bug

I'm getting the following exception in my project after updating to 2.0.0-Beta and running ./gradlew dokkaGenerate:

Execution failed for task ':coil-core:dokkaGenerateModuleHtml'.
> A failure occurred while executing org.jetbrains.dokka.gradle.workers.DokkaGeneratorWorker
   > Illegal use of flexible type deserializer.

Expected behaviour The build to finish successfully.

To Reproduce Check out this branch and run ./gradlew dokkaGenerate.

Dokka configuration None: I removed the Dokka configuration on that branch to reduce confounding factors.

Installation

• Operating system: macOS
• Build tool: Gradle v8.10.2
• Dokka version: 2.0.0-Beta

Additional context I found a similar report from an older Dokka version, however I don’t use the dynamic JS type in my project (maybe a dependency does?).

Observation: When I comment out the KDoc of the forEachIndices function in collections.kt, the task :coil-core:dokkaGeneratePublicationHtml succeeds.

- /** @see forEach */
+ ///** @see forEach */
  internal inline fun <T> List<T>.forEachIndices(action: (T) -> Unit) {
      for (i in indices) {
          action(get(i))
      }
  }
