I was trying to install this layer on my Spacemacs (0.300.0, develop branch, on Emacs 26.2).

Following the instructions, adding this to my .spacemacs, in dotspacemacs-configuration-layers:

(scala-lsp :location
          (recipe :fetcher github
                  :repo "zheli/layer-scala-lsp"))

gives me this warning on restart (or reload):

Warning: Unknown layer scala-lsp declared in dotfile.

Reading this issue on Spacemacs, it looks like external layers are not supported. Maybe the instructions mean to put the layer in dotspacemacs-additional-packages? I know for a fact that Github recipes work there ...

As the issue emacs-lsp/lsp-mode#973 says, should use lsp-mode only, because metals already in lsp-mode .

emacs-lsp/lsp-mode#973 (comment)

When using the completion, instead of simply adding the name of the function/variable/... it also adds types.

Example: When using completion (via the tab key) for this snippet

def test = help_str.to

I get this result:

def test = help_str.toString(): String

instead of something like that:

def test = help_str.toString

Hi,

thanks for the layer btw. I got it working and it shows function arguments etc.
But I miss dot completion, does this work on your system?
(with "dot completion" I mean accessing available fields/methods of an object like myObj.head)
