.cabal was modified manually, please use --force to overwrite.

Hi, I'm trying to use an external git repo as an extra-dep in stack-to-nix and getting the error

.cabal was modified manually, please use --force to overwrite.

It doesn't seem like this is the case as I've tried regenerating it from the hpack but it reports the same. If I delete the cabal file, then it works.

Hm, maybe different versions of hpack? I would hope that different versions would produce the same .cabal file from something with the same spec-version...

[locallycompact]

Is there a way to grab the generated copy of the cabal file for the nix version of that build to compare?

[michaelpj]

Maybe just run the hpack yourself? If you build haskell-nix.haskellPackages.hpack.components.exes.hpack and run the hpack from there yourself on your package.yaml that'll presumably give you the same objection.

I think this might be a bug in haskell.nix. If both a .cabal file and a package.yaml file are present in a directory should we be running hpack at all or just using the .cabal file?

I hit this error by having both a .cabal file and package.yaml file.

I think this has been fixed for cabalProject (it now prefers .cabal file over package.yaml if both are present). I am not sure about stackProject though.
