dotfiles VS nvim-jdtls

I would say that my config is not the best, but it does contain a few gems I have found throughout my short time vimming: https://github.com/UnrealApex/dotfiles

There are probably a plugins for this, but a plugin that setups up LSP for you, and a easy debugging support. I use Coc.nvim because I found it extremely difficult to configure native LSP for Java development(what I primarily do right now because I'm taking a Java programming class). My setup consisted of lsp-config + mason.nvim + nvim-cmp As for debugging, nvim-dap was kind of confusing and vimspector doesn't have the best Neovim support. I'm not used to setting up debugger configurations as prior to Neovim, I used VS Code which did that automatically.

How do I configure debugging using nvim-dap? I am trying to get Java debugging(nvim-dap) working but to no avail. Trying to configure nvim-dap has been really frustrating, but I know that getting it set up is rewarding. Any ideas on how to get it set up easily? I'm looking for an in depth explanation that is beginner friendly. Most of the resources I've found haven't really been thorough although u/rockerBOO's guide certainly did help. Below is what I have tried to configure. What am I doing wrong? Is there anything I need to add? For reference, here is my Neovim config: UnrealApex/dotfiles(excluding the debugging stuff as I haven't committed it yet).

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.

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.
