Answer 1

Are you using https://github.com/sbt/sbt-unidoc ? If not, perhaps it may be the solution you're looking for.

Answer 2

Something like this should work:

  val scalaVer = "2.12"
  val commonSettings: Seq[Def.Setting[_]] = Seq(
    autoAPIMappings := true,
    apiURL := Some(url(s"file:${baseDirectory.value.getAbsolutePath}/target/scala-${scalaVer}/api")),
  )
  lazy val a = (project in file("a")).settings(commonSettings)
  lazy val b = (project in file("b")).settings(commonSettings)
