Inappropriate "not listed in your .cabal file's other-modules" error

[maximpichler]

I'm getting the following error:

Dummy:0:0:Error:These modules are needed for compilation but not listed in your .cabal file's other-modules for ‘main’ :
    Utils

This is in spite of the fact that Utils is listed in the other-modules section.

$ cat xyz.cabal
cabal-version: 3.0
name:          xyz
version:       0.1.0.0
build-type:    Simple

executable xyz
  ghc-options:    -Wall
  main-is:        Main.hs
  other-modules:  Utils
  build-depends:  base ^>=4.19.1.0
  hs-source-dirs: app

$ cat app/Main.hs
module Main where

import Utils (x)

main :: IO ()
main = print x

$ cat app/Utils.hs
module Utils where

x :: Int
x = 42

There is no hie.yaml file.

Hi, thank you for the bug report! Can you provide the logs of hie-bios debug app/Main.hs?

[maximpichler]

It seems that the error only occurs with the check subcommand, not with the debug one. Here is the full output for both.

[fendor]

I think that's a bug in hie-bios's module checking logic. Perhaps a target guessing bug, since we see [("app/Main.hs","app/Main.hs")] is missing "app/Utils.hs".

To me, this code path has a rather low priority, and is only used for testing. Do you have a specific need?

[maximpichler]

I stumbled across this while debugging an issue with haskell-language-server and eglot. From what you say it seems that it is a red herring. Will report back if I come across any evidence to the contrary.
