hie-bios can't load packages with build-tool-depends

[maksbotan]

Hi,

I try to use haskell-ide-engine with this project: https://gitlab.com/morley-framework/morley

My hie.yaml:

cradle:
    cabal:
        - path: "code/morley"
          component: "lib:morley"
        - path: "code/morley/test"
          component: "morley:morley-test"

When I try to load tests in hie:

$ hie code/morley/test/Test/Michelson/Runtime.hs 
...
Dumping diagnostics:


/home/maks/Projects/SRK/morley/code/morley/test/Test/Michelson/Runtime.hs: FAILED
	"could not execute: tasty-discover"

This is probably related to the fact that tasty-discover is used as build-tool-depends in the cabal file:

test-suite morley-test
  build-tool-depends:
      tasty-discover:tasty-discover

For some reason hie does not see it, while cabal new-build morley --enable-test passes.

Env:

$ ghc --version
The Glorious Glasgow Haskell Compilation System, version 8.8.3
$ hie --version
Version 1.4 x86_64 ghc-8.8.3
$ cabal --version
cabal-install version 3.2.0.0
compiled using version 3.2.0.0 of the Cabal library

                }
            },

I think this might be related to #125

[maksbotan]

Maybe it is, however I'm using pure Cabal cradle. Maybe they share some code in this regard...

Just in case, a temporary workaround could be install tasty-discover globally.

[maksbotan]

Sure, that's what I did :)

FWIW, the title here isn't quite true in general since I'm happily using HLS on a project involving c2hs. I suspect the difference there is that the build tool is only ever run on .chs files, which hie-bios ignores completely.

(This does mean that I need to manually kick c2hs, via cabal, when I change a .chs file, in order for the changes to show up in my editor, but I'd expect nothing less right now.)
