2 months ago Hi, thank you for bug report and the detailed instructions!
HLS's support for build-type: Custom is generally speaking not great. So, I am not surprised there are a couple of sharp edges.
I can not reproduce exactly the same error, though, on the first run, I am getting:
Failed to run ["cabal","v2-repl","/home/hugin/Downloads/my-lib/test/Spec.hs"] in directory
"/home/hugin/Downloads/my-lib". Consult the logs for full command and error.

Saved package config file is outdated:
• the Cabal version changed from Cabal-3.12.1.0 to Cabal-3.10.3.0
Re-run the 'configure' command.
Error: [Cabal-7125]
repl failed for my-lib-0.1.1.0.And after I ran cabal build all --enable-testing once, it started working altogether, and I can't get it to fail again :thinking:. However, it is really slow to load the project.
Full disclosure, I am not running the nix flake as I didn't really need it.

Your environment
I prepared a small project to reproduce the issue. (Nix Flakes are required)
my-lib.tar.gz
Which OS do you use? NixOS on WSL2
Which version of GHC do you use and how did you install it? GHC 9.2.8 from Nix Flakes
Which LSP client (editor/plugin) do you use? VS Code + Haskell plugin Which version of HLS do you use and how did you install it? 2.4.0.0 from Nix Flakes
Have you configured HLS in any way (especially: a
hie.yamlfile)? No.Steps to reproduce
Prerequisites: Nix Flakes
From CLI: (reproduce the issue probabilistically)
nix develophaskell-language-server-wrapper src/Lib.hs test/Spec.hsFrom VS Code:
nix developcode .test/Spec.hsand wait for the language server to start. At this point, there should be no errors.src/Lib.hs.Expected behaviour
No compile errors are reported
Actual behaviour
Could not load module 'Lib'intest/Spec.hs.The tricky part is that no errors occur when only one of
Lib.hsorSpec.hswas opened, but onceLib.hsis opened, errors start appearing inSpec.hs.Debug information
The following is logs when
haskell-language-server-wrapper src/Lib.hs test/Spec.hsfailed. (Here,haskell-language-server-wrapperis configured with Nix to use--debug --logfile hls.log. This setting exists because arguments cannot be passed to the Haskell language server from VS Code.)The following is VS Code case.
