'xsbt ghpagesPushSite' failing with java unidoc: 'fatal: Not a git repository'

[erikerlandson]

I have a smallish java project here:
https://github.com/erikerlandson/gibbous/tree/unidoc-issue

I attempted to set it up for generating javadoc per the instructions on your site. You can browse my sbt setup at the branch linked above.

xsbt previewSite seems to be generating what I expect, but xsbt ghpagesPushSite is failing in a strange way. I have attached the full output, but the error is this:

[info] Loading settings from build.sbt ...
[info] Set current project to gibbous (in build file:/home/eje/git/gibbous/)
[error] fatal: Not a git repository (or any parent up to mount point /home)

full output

For me it looks like sbt-ghpages plugin got something that was unexpected (missing git repository). Therefore I am not sure if that is related to sbt-unidoc.

I'm at a loss to guess what git repo could be missing. I executed xsbt ghpagesPushSite in my git repo. It has a gh-pages branch constructed as usual.

I see that you are adding some mappings in your repo. And the sbt-ghpages plugin runs some git commands depending of the mappings at least from my initial impressions. I would try digging there. :)

Found a solution here: sbt/sbt-ghpages#40
~/.sbt/ghpages was stale somehow.
