Nonzero exit code (1) running git when running ghpagesPushSite

[jhnaldo]

Hi, I'm a maintainer of ESMeta project. We're using sbt-ghpages to publish our API docs. Thanks for developing a good tool. However, we recently had a problem when running ghpagesPushSite as mentioned in es-meta/esmeta#255 with the following message:

$ sbt ghpagesPushSite

Can you guide us on how to resolve or debug this problem?
