Resolving dependencies...
cabal: Could not resolve dependencies:
[__0] trying: haskell-language-server-1.2.0.0 (user goal)
[__1] trying: haskell-language-server:+refineimports
[__2] unknown package: hls-refine-imports-plugin (dependency of
haskell-language-server +refineimports)
[__2] fail (backjumping, conflict set: haskell-language-server,
hls-refine-imports-plugin, haskell-language-server:refineimports)
After searching the rest of the dependency tree exhaustively, these were the
goals I've had most trouble fulfilling: haskell-language-server,
haskell-language-server:refineimports, hls-refine-imports-plugin
