neovim-luca VS nvim-jdtls

Hello guys. I installed neovim using my own nix flake: https://github.com/quoteme/neovim-luca

I recommend that you do not configure jdtls like the other language servers, it is better to use the nvim-jdtls plugin.

Java is actually pretty good with Neovim, jdtls and this plugin. One of the best language servers and I'm using it on a regular base with medium to large projects, mostly spring-based. No Android though.

I can get by with https://github.com/mfussenegger/nvim-jdtls

This and this provided no viable solutions for me

I tried to configure jdtls for my NeoVim I followed https://github.com/mfussenegger/nvim-jdtls install instruction. and I faced this error does anyone successfully configured jdtls ? help T ^ T

Am I adding it to the wrong configuration option? Some places I see it added as a referencedLibary - https://github.com/mfussenegger/nvim-jdtls

Sure. Any server that lspconfig supports will work. But for java development is better if you use nvim-jdtls. The documentation in lsp-zero has a guide on how to setup nvim-jdtls.

Here' my java.lua for nvim-jdtls which solves the nil issue and add more features.
