Scala language server with rich IDE features.

See full instructions in the Metals documentation:

https://scalameta.org/metals/docs/editors/vim#using-an-alternative-lsp-client

Note: that if you're using [nvim-metals](https://github.com/scalameta/nvim-metals), that plugin fully handles the setup and installation of Metals, and you shouldn't set up Metals both with it and `lspconfig`.

To install Metals, make sure to have [coursier](https://get-coursier.io/docs/cli-installation) installed, and once you do you can install the latest Metals with `cs install metals`.
