nvim VS nvim-jdtls

Not OP, but I had the same question. I would prefer to manage my nvim config not the NixOS way.

You might also have a look at my recent commit on my "develop" branch https://github.com/Allaman/nvim/commit/1b587f16d074755c94a8692925dfcbf5344fb7d4

Allaman's Neovim Config

In my config I have these lines

From time to time I build my Dockerfile to test if my config would run on a fresh system or if an issue might only be related to my host

It is working for me but I am not aware of any "special" setting I made. here is My cofing maybe you can get an idea. ([go](https://github.com/Allaman/nvim/blob/main/lua/config/go.lua), [lsp](https://github.com/Allaman/nvim/tree/main/lua/config/lsp)]])

There is only one LSP running for in my Neovim My config for reference

Thanks for your inspiration ;) https://github.com/Allaman/nvim/commit/78e32885972947240b0907df6a8a1cceea9fce19

in the last couple of weeks I noticed some Neovim crashes (segmentation faults says my terminal) and I wonder if I am alone? Before that I never had crashes and now at least two a day. Neovim head and here is my config

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.
