How do I use Github Copilot with lsp-zero?

[githorse]

I've set up lsp-zero according to the recommendations, including this in packer.lua:

use {
	'VonHeikemen/lsp-zero.nvim',
	branch = 'v1.x',
	requires = {

		-- LSP Support
		{'neovim/nvim-lspconfig'},             -- Required
		{'williamboman/mason.nvim'},           -- Optional
		{'williamboman/mason-lspconfig.nvim'}, -- Optional

		-- Autocompletion
		{'hrsh7th/nvim-cmp'},         -- Required
		{'hrsh7th/cmp-nvim-lsp'},     -- Required
		{'hrsh7th/cmp-buffer'},       -- Optional
		{'hrsh7th/cmp-path'},         -- Optional
		{'saadparwaiz1/cmp_luasnip'}, -- Optional
		{'hrsh7th/cmp-nvim-lua'},     -- Optional

		-- Snippets
		{'L3MON4D3/LuaSnip'},             -- Required
		{'rafamadriz/friendly-snippets'}, -- Optional
	}
}

Now I've followed the instructions to install and enable Github Copilot for Neovim. Out of the box, :Copilot status tells me that <Tab> map has been disabled or is claimed by another plugin. Attempts to debug that are so far unsuccesful.

Ideally I'd like completion to work seamlessly with Copilot and other autocompletion sources. But maybe I don't even need those when I'm running Copilot? Looking for advice here. Has anyone successfully gotten Copilot working with lsp-zero?

First thing I suggest is updating lsp-zero's version: Change the branch from v1.x to v3.x.

Next step is to delete whatever configuration you have for lsp-zero right now, and replace it with this:

local lsp_zero = require('lsp-zero')

lsp_zero.on_attach(function(client, bufnr)
  -- see :help lsp-zero-keybindings
  -- to learn the available actions
  lsp_zero.default_keymaps({buffer = bufnr})
end)

-- see :help lsp-zero-guide:integrate-with-mason-nvim
-- to learn how to use mason.nvim with lsp-zero
require('mason').setup({})
require('mason-lspconfig').setup({
  handlers = {
    lsp_zero.default_setup,
  }
})

This particular config does not offer the same set of features as v1.x had enabled by default. But copilot should work with it.

if you want to re-enable some of the features from v1.x, read this guide: Migrating from v1 branch
