Is is possible to use unidoc with subprojects that have mutually exclusive scalac options?

[jackkoenig]

I'm using Scala 2.12/2.13.

My basic problem is that I have a multi-project build that I want unified ScalaDoc for. I have two projects that must have different scalac behavior (one needs a compiler plugin, one must not have the compiler plugin). It seems that sbt-unidoc runs ScalaDoc on both projects together with the same arguments, thus I have a problem. Is it possible to have unified ScalaDoc while having different compiler behavior for the different projects or is this just not a possible thing?
