lsp-types-2.0.0.0 fails to build in current Stackage Nightly:

My guess is that you forgot to include metaModel.json in .cabal. It might be good to build from sdist in CI.

I cannot build lsp-test successfully, it says "unknown package: extra"

[juhp]

@7c78 quite unrelated and you just need to run cabal update first to initialize the package list.

[7c78]

@juhp sorry, my bad. I usually do not have to use cabal update when I set up a Haskell environment with Nix.

I pushed lsp-types-2.0.0.1 with the fix.
