It's actually pretty easy. First, I inspected doc to see what it was (inspect doc on the sbt prompt), noticed it was a task, and proceeded with declaring a dependency on itself on build.sbt:

doc in Compile <<= doc in Compile map { (file) =>

  file
}

That thing I used to execute bash is the same library as scala.sys.process, so you can look up Scaladoc for that. This was tested on SBT 0.12.2, and I think there might be a small difference on SBT 0.11.x or 0.10.x.
