I believe the web docs need to be built separately according to the instructions here.

Did you give those a shot?

It's annoying to have a separate thing with new dependencies in order to build the web docs, but that's how it is at the moment.

I finally came to realize that there is a special maven target to build the scaladocs, although arguably a very unintuitive on: mvn verify. So now I have scaladocs for each package, but not for the whole spark project. Specifically, build/docs/api/scala/index.html is missing. Indeed the whole build/docs/api directory referenced in api.html is missing. How do I build it?
