Import stuff like wildcards you aren't always prompted to with LSP.
Update wildcard-importer-alist
until satisfied like so:
(setq wildcard-importer-alist
(wildcard-importer-with-extensions
'((scala-mode ("import foo.bar" . "tips on when to use foo.bar")))))
(In your dir-locals.el
would probably be best). And then invoke: M-x wildcard-importer-import
.
