This PR vendors a copy of https://github.com/lefou/mill-vcs-version
inside the Mill repo.
mill-vcs-version
is necessary for re-bootstrapping on top ofmain
.mill-mima
ormill-scalafix
are linters that can be disabled duringthe re-bootstrapping process and turned on again later when the
third-party plugins are available, but
mill-vcs-version
is needing tocompute versions during the bootstrapping/dogfooding process and cannot
simply be skipped.
An alternative would be copy-pasting code into
build.mill
as atemporary hack, but I think it's better to just vendor a full copy of
the upstream codebase.
mill-vcs-version
is a pretty small and stablecodebase, so the overhead of maintaining a vendored copy should be
manageable.
