Java-Language-Server not showing warnings/errors?

[MATOO-Dev]

I'm trying to set up LSPs on NixOS as a home-manager module. Currently my config.plugins.lsp looks like this:

lsp = {
    enable = true;
    servers = {
        java-language-server.enable = true;
        nil_ls.enable = true;
    };
};

The Nix language server functions just fine, but the Java one doesn't show any warnings/errors. Is there an option I'm missing or do I need to install an additional package or something?

:LspInfo returns the following:

I hope you got it fixed but I had the same issue. Look at my nix dotfiles. Specifically User/Programs/Nixvim/lsp.nix. That is what I have so far and now I have java-language-server and jdtls running at the same time. I still need to tweak this but two LSP's is better than 0. Still working on the DAP too lol
