I ran into the same problem. Could be a conflict with the Scala plugin perhaps, since this plugin is using Scala 2.12 and I suppose the Scala plugin is on 2.13 ?!

[Clindbergh]

Me too. Is there a workaround? Does it work with a previous IJ version?

[avdv]

@Clindbergh Try to disable the Scala plugin and restart the IDE. Does it work now?

Unfortunately not.

[Clindbergh]

@avdv Can you tell me what IJ version and which plugins you're using so I can try to copy your environment?

While reading through the logs, I noticed that the plugin version I have installed from the marketplace is version 0.3.42, whereas the latest release currently is 0.3.46. Downloading the zip file from the releases page and trying to install the plugin from disk shows an error though:

So, what I did:

1. unpack the zip file
2. unpack the META-INF/plugin.xml file from intellij-haskforce-0.3.46.jar
3. change the line <idea-version since-build="211.6693" until-build="211.*"/> to <idea-version since-build="211.6693" until-build="213.*"/>
4. update the entry of the jar file: zip -u intellij-haskforce-0.3.46.jar META-INF/plugin.xml
5. create a zip file from all jars again: zip -r ../haskforce-0.3.46.zip HaskForce/
6. install the modified zip file

This seems to work 🎉 (correction: works better, but there are other errors)

Thanks @avdv! While I was able to install even Release 0.3.45 this way, I wasn't able to setup the haskell SDK of stack. I am trying to select them in the Project Structure > Platform Settings > SDK > Haskell > Haskell SDK home path, but for both of these paths

$ which stack ghci
/c/Users/Me/AppData/Roaming/local/bin/stack
/c/ProgramData/chocolatey/lib/ghc/tools/ghc-8.10.2/bin/ghci

I receive an error message Cannot Detect SDK Version - Probably SDK installed in ... is corrupt. What path have you set there?

It is a project based on stack and I did try to import it as described in the Wiki.

For me, it is just /home/claudio -- but I am on NixOS, so that may be different.

@avdv: I switched to NixOS a couple months ago. Do you mind sharing your Haskell environment setup or a simple flake of one of your projects? That would be awesome!

Hi @Clindbergh ,

I am using haskell-language-server with Emacs / VSCodium currently. So I don't have a setup using haskforce at the moment.
