Tests fail with stack 2.1.1

[gelisam]

I am creating an issue here so that users find it if they experience an issue with stack 2.1.1, but this is not a bug in hawk, it is a bug in stack 2.1.1 which is fixed in stack at commit 61edf6b824ac53ea9d20bd21c3e0d6a385f29ea1. For some reason, at the time of writing, using stack upgrade --git obtains a version of stack which does not include that bugfix, I don't know why.

stack 2.x now creates an environment file controlling which packages are visible to test suites. That environment file is supposed to list all the dependencies listed in the .cabal file for that test suite, but the bug in stack 2.1.1 is that it doesn't include the library provided by that same .cabal file even if it is listed. Since hawk needs to load modules from the haskell-awk library, the test suite fails.

See https://github.com/commercialhaskell/stack/issues/4896 and https://github.com/commercialhaskell/stack/pull/4921 for details.

You can obtain a version of stack which includes the bugfix with stack upgrade --git --git-branch stable.
