stackProject does not seem to recognize the compiler field in stack.yaml

[poscat0x04]

I'm trying to compile haskell-language-server with ghc 8.10.1 (the nix expression I'm using: hls-nix) and for some reason haskell.nix chose to use ghc 8.8.3 to build the project instead of ghc 8.10.1

to reproduce, run nix build --argstr version "8.10.1" -f . exes.haskell-language-server inside the repo.

Manually calling stack-to-nix does not have this issue, which is weird

[michaelpj]

Are you using a recent version of haskell.nix? Is the stack-to-nix that you used the same as the one your haskell.nix is using?

[poscat0x04]

Yes, I'm using HEAD. Yes.

We also seem to be affected by this.

Using haskell.nix 0d781c0 (current HEAD).

Our stack.yaml includes:

resolver: lts-17.1
compiler: ghc-8.10.4

But haskell-nix.project ends up compiling ghc 8.10.3, unless we override compiler-nix-name.
