Module not found with custom hie.yaml and bazel

[teto]

Subject of the issue

When opening files with atom/vscode, I have Module not found errors. I use a multicradle with a per-subfolder cradle similar to this one: haskell/hie-bios#250 (comment) , i.e., I have a list of flags in a file on a per-cradle basis. aka (.tmp/subfolder2.flags for the cradle matching path "./subproject2")
If I open file/module A and vscode+hls says file/module B missing. If I run hie-bios check A, it returns 0 with no output (which I assume mean my flags are good and thus contradicts vscode output). the path to B appears in hie-bios flags A.
Now if I open B, the error about the missing B disappears :s

Your environment

• Output of haskell-language-server --probe-tools or haskell-language-server-wrapper --probe-tools
  • This command is available since version >= 0.4.0.0

My version of hls is 5729c2ea119e9d48c136cc75c377d41fec811dde (recent).
haskell-language-server version: 0.4.0.0 (GHC: 8.8.3) (PATH: /home/teto/.cache/bazel/_bazel_teto/32070fb26dd3cfe8bd075800f8bb83d1/execroot/toplevel_workspace/bazel-out/k8-fastbuild/bin/external/hls/haskell-language-server-0.4.0.0/_install/bin/haskell-language-server)
Tool versions found on the $PATH
cabal:		Not found
stack:		2.3.1
ghc:		8.8.3

• Which lsp-client do you use: atom/vscode (possibly neovim)
• Describe your project (alternative: link to the project): Closed source and we use bazel so no cabal/stack
• Contents of hie.yaml: akin to silly question about none cradle hie-bios#250 (comment)

Steps to reproduce

can't share the code sry :'(

Expected behaviour

No error about missing module

Actual behaviour

Error about missing module

Include debug information

Execute in the root of your project the command haskell-language-server --debug . and paste the logs here:
So I can't paste all the logs but here is an excerpt. Because I use bazel to build we don't have .cabal files and also my hie.yaml ignores all the files in bazel-out/ (where haskell packages can be stored) which points at my /home/teto/.cache/bazel/_bazel_teto/

Output from setting up the cradle Cradle {cradleRootDir = "/home/teto/nova/jinko", cradleOptsProg = CradleAction: Default}

This seems unlikely to be correct. It should almost definitely not be a Default cradle. Is the cradle root correct?

[teto]

thanks for always taking the time to answer my issues.
The cradle root is correct. Inside this root /home/teto/nova/jinko, there is a symlink /home/teto/nova/jinko/bazel-bin that points at home/teto/.cache/bazel/_bazel_teto/. As in my hie.yaml I have an entry path: ./. => cradle: none I think /home/teto/.cache/bazel/_bazel_teto/32070fb26dd3cfe8bd075800f8bb83d1/execroot/toplevel_workspace/bazel-out/k8-fastbuild/bin/simwork/examples/DummDiff@scenarized_Main.hs should be covered by a none cradle ? Also /home/teto/.cache/bazel/_bazel_teto/32070fb26dd3cfe8bd075800f8bb83d1/execroot/toplevel_workspace/bazel-out/k8-fastbuild/bin/simwork/examples/DummDiff@scenarized_Main.hs may be loaded because I reference this very file as a bios flag in another cradle .

Not sure what "default" means there (implicit ?)

[fendor]

Late answer (but better late than never I assume):

Easiest way to check is to use hie-bios debug <filepath> and look at the output.

Not sure what "default" means there (implicit ?)

Default means basically: use straight "ghc" with no further options. With current changes to ghcide, this basically means, don't do anything, as we don't discover targets implicitly.

@teto do you continue having this issue or did you find any workaround? From the comments i guess it should work with the correct explicit hie.yamlfile

[teto]

I've managed to squash some of the issues: explnation at haskell/hie-bios#275.

Some other errors elude me but I think I can create more specific issues
