Error Message

Fail on initialisation for "/Users/username/src/github.com/username/my-project/Setup.hs".
Could not obtain flags for: "Setup.hs".

This module was not part of any component we are aware of.

Component: ChLibName ChMainLibName with source directory: ["src"]
Component: ChExeName "my-project-exe" with source directory: ["app"]
Component: ChTestName "my-project-test" with source directory: ["test"]

To expose a module, refer to:
https://docs.haskellstack.org/en/stable/GUIDE/
If you are using `package.yaml` then you don't have to manually expose modules.
Maybe you didn't set the source directories for your project correctly.

stack build is completed successfully. Do you have any idea?

Setup.hs is a special file and hie does not have support for it yet. You should be able to open other files (inside src or exe dirs) though. See https://github.com/haskell/haskell-ide-engine/issues/1650

@jneira Thank you. I will watch #1650 discussion.

Feel free to reopen, if it turns out, it wasnt a duplicate of #1650
