It would also be nice if it did a ```stack install package``` and the equivalent for cabal in order for the error to clear, otherwise it stays around and you...

Same issue but i notices spelling only stops working if i set a custom `g:pandoc#syntax#codeblocks#embeds#langs` without it spelling works fine.

I checked and the my problems is traceable to `haskell` in `g:pandoc#syntax#codeblocks#embeds#langs` so its not only `java`
