buildifier-fix broken On NixOS #616

Closed gdeest closed 5 years ago

buildifier-fix is currently broken for me on master:

Cannot reproduce. You're in a nix-shell, and I'm trying the exact same commit as you. That's worrying... I know this should not be a solution, but try bazel clean --expunge? If that works then it's a bug, but likely a bug upstream in rules_go (hence would need to file a ticket there). I really don't see how this kind of hermeticity issue would creep in, however.

Indeed, clean --expunge seems to have solved it. Might be hard to reproduce …
