@3flex where you able to understand what are the build failures? It seems we have failing tests plus generateDocumentation is failing

[3flex]

I believe it's now blocked thanks to an out of date transitive dependency of mockk and also Android Gradle Plugin incompatibility with Java 16.

Mockk will be fixed soon enough I expect but I can manually add the required dependency version to fix it in the meantime.

I can't find compatibility info for AGP. They probably only officially support the JDK version shipped with Android Studio (currently 11?) So Android tests should probably be skipped on other JDK versions.

I have to check the generateDocumentation task.

Waiting for separate Kotlin bump
