Client 1 quit with exit code 13 and signal 0

[xebcam]

Hi. I followed the installation and configuration examples in the readme but when I open a .java file I get Client 1 quit with exit code 13 and signal 0 as a message and lua print(vim.inspect(vim.lsp.buf_get_clients())) just return an empty table {}. I'm really a noob configuring nvim with lua so any help would be appreciated.

I use Archlinux so I installed the jdtls thru the AUR.

lsp.log shows this when I open a java file

This is my configuration in .config/nvim/ftplugin/java.lua

And this is my init.lua

require "user.options"
require "user.keymaps"
require "user.plugins"
require "user.colorscheme"
require "user.cmp"
require "user.lsp"
require "user.telescope"
require "user.treesitter"

You can see that I'm not requiring the configuration java.lua in this file as it's not stated that it needs to be in the readme (doing so doesn't work either).

I'm sorry I just realized that my workspace_dir is not set properly. Changing it to a valid directory fixed the problem.
