Breaks in git worktree

[sellout]

If I try to load the sbt-microsites plugin on a git worktree in a different dir than my original clone, I get an error like

org.eclipse.jgit.errors.NoWorkTreeException: Bare Repository has neither a working tree, nor an index

So, the root cause of this seems to be a bug in JGit with an unmerged “PR”. Which is used by sbt/sbt-git, which is used by sbt/sbt-ghpages, which is used here.

@sellout Would using ConsoleGit instead of JGit help as a workaround for this issue? https://github.com/sbt/sbt-git/blob/5c72a29953c529b29f39e1d0e771406a4c05390f/src/main/scala/com/typesafe/sbt/SbtGit.scala#L112

@raulraja Maaaaaaaybe … I’m not sure if I’m setting that correctly. I tried

SbtGit.GitKeys.gitRunner := sbtgit.ConsoleGitRunner

both at the top level of my build.sbt, and also in my standardSettings (which is used by every subproject).

@juanpedromoreno any ideas? Maybe one of those in ThisBuild ^^^

Nop, no idea why it's not possible to override that sbt config :( . I'd need more time to look at this issue, and a way to reproduce it.
