Couldn't create Haskell module because Cabal file can't be found

I am setting up a fresh machine, have installed Stack (and made sure it’s in the PATH), IDEA 2020.2 Beta (because I like living on the edge), and the latest IntelliJ Haskell plugin (v. 1.0.0-beta76).

After trying to import a Stack project, I am being presented with the following error:

Couldn’t create Haskell module because Cabal file can’t be found in W:\Projects\icfpc-2020

After that, an informational message is shown:

Can not add package . as module because W:\Projects\icfpc-2020 does not contain Cabal file or Cabal file can not be parsed

I can’t share the project (yet), because it’s part of my ICFP Contest submission (and will be available in a couple of days), but it’s a pretty standard Stack package - with no Cabal file.

Alright, so this was a corner case, only valid when a project cannot be compiled. Fair enough, in such a case I’ll close the issue. Thanks for explanation!

That happened to me because the Stack executable was not found, mine is in /usr/bin/stack but the extension looks into /usr/local/bin/stack so I created that directory and created a symbolic link using sudo ln -s /usr/bin/stack /usr/local/bin/stack and now it works without problems
