Multiproject - "fatal: Not a git repository (or any of the parent directories): .git"

The Problems

I have a multiproject that I am struggling to make work with sbt-ghpages and SBT 0.13.16. The subprojects are called root and demo, in similarly named directories. I would like to be able to generate Scaladoc for each of the subprojects, and push them both to gh-pages somehow.

1. The first problem manifests in the multi git branch:

   $ sbt
   .. lots of output ...
   
   Reference to undefined setting:
   web3j-scala/*:gitRemoteRepo from web3j-scala/*:ghpagesUpdatedRepository ((com.typesafe.sbt.sbtghpages.GhpagesPlugin) GhpagesPlugin.scala:36)
   

   This problem was reported September 8, 2015 in sbt/sbt-git#97, and the solution suggested by @wpc009 on Mar 14, 2016 can be rewritten for SBT 0.13.16+ as:

    GitKeys.gitReader in ThisProject := baseDirectory(base => new DefaultReadableGit(base)).value,
   

   However, adding that line into common settings does nothing.

   BTW, the root project in the master git branch is not in a subdirectory, so the above problem does not manifest for that git branch. However, ghpagesPushSite does not work for the demo sbt subproject in that branch for the same reason: the .git directory is a sibling of the demo directory, instead of the .git directory being a child of the demo directory.

2. The second problem: Given N different subprojects, each of which might want to publish its own Scaladoc, I can image two ways of structuring the Scaladoc; are either of these options possible? a. N different git branches would hold the generated Scaladoc for each of the N sbt subprojects; the branches might be named after the sbt subprojects b. N different subdirectories would be created in the gh-pages branch, under the usual latest/api/ directory; the subdirectories might be named after the sbt subprojects. For example:

   http://mslinn.github.io/web3j-scala/latest/api/project1name/index.html http://mslinn.github.io/web3j-scala/latest/api/project2name/index.html http://mslinn.github.io/web3j-scala/latest/api/project3name/index.html http://mslinn.github.io/web3j-scala/latest/api/project4name/index.html

   What is the recommended way forward?

The solution(s) to both of these questions/problems should probably be added to the README for this project.

I am having the same issue, following the docs leads me to the same error. Is there a way to fix this?
