vim-vsnip VS nvim-jdtls

My go to these days has been https://github.com/hrsh7th/vim-vsnip. It is compatible with LSP and VSCode snippet format. Since it is in pure VimScript you don’t need to battle configuring python just to get the plug-in to work.

I first started by reading some tutorials but most of those used parser combinators. For me, parser combinators always caused some issues sooner or later (at least in Lua when trying to parse recursive / nested nodes). An example project that uses this technique is vim-vsnip: https://github.com/hrsh7th/vim-vsnip/blob/master/autoload/vsnip/snippet/parser.vim. Later, I found out that Luacheck uses a different approach which I liked better: https://github.com/lunarmodules/luacheck/blob/master/src/luacheck/parser.lua. That's the project that helped me the most while writing my own parsers for different snippet engines.

This plugin could use it? hrsh7th/vim-vsnip

I am not a snippets expert, I don't even currently use snippets. However, I know that both LuaSnip and vim-vsnip can load these vscode style snippets. So my recommendation would be to get the snippets and use one of those two snippet plugins.

For autocompletion I use the nvim-cmp plugin. If you're not coding, it might be overkill. But during writing it helps me a lot, because it autosuggests words that I used in the current buffer, too. The most popular autocomplete plugins should be compatible with the most popular snippets engines like vim-vsnip.

Have you ever wondered how to have a snippet completion in VSCode so you can write Julia code fast but in Neovim? Fear not! vim-vsnip is the plugin you need. This plugin supports LSP/VSCode's snippet format. But first, you need to install cmp-vsnip for this plugin to be sourced to nvim-cmp. Oh btw, these three plugins: nvim-cmp, vim-vsnip, and cmp-vsnip → are made by the same person which is actually cool! If you want to support them, become a sponsor! (I am poor so I cannot sponsor yet 😔)

I believe you want the second variant. Then you should install some snippet plugin like vsnip or luasnip and config it with your completion engine.

https://github.com/hrsh7th/vim-vsnip says it supports vscode style snippets, so apparently you could use https://marketplace.visualstudio.com/items?itemName=kaffeine.advanced-drupal-8-snippets with that plugin.

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.
