== VSCode + Language Support for Java (TM) by Red Hat extension ==

Unfortunately the extension makes use of dynamically loaded libraries which nix cannot accomodate out-of-the-box. Fortunately there's a simple solution in the use of [https://github.com/Mic92/nix-ld nix-ld]. Here's a simple flake.nix to get you started (I'll focus on the devShell part for brevity):
