Jump to definition in java libraries

[antosha417]

Hi!
Is it possible to gd from scala to java code using metals?
This seems not to work for me.
When I do :lua vim.lsp.buf.definition() on some java code that I use in scala project nothing happens.
There is no errors in metals.log

Hey @antosha417! Yes, this should totally work. Is this some methods in a Scala file, or are you actually in a Java file? If you're in a Java file and looking for some navigation you'll want to make sure you have java in the filetype autocmd that starts Metals. Like:

  api.nvim_create_autocmd("FileType", {
    pattern = { "scala", "sbt", "java" },
    callback = function()
      require("metals").initialize_or_attach(metals_config)
    end,
    group = nvim_metals_group,
  })

Do you have that? Also, could you take a look at the :MetalsRunDoctor? Do you see anything funky in there?

It turns out I did have java in the pattern. So metals was not attached.
