Anyone know anything about getting a kotlin language server running on NixOS? I can't find one in nixpkgs, and building the one on github (https://github.com/fwcd/kotlin-language-server) fails for me.

Or optionally: anyone know how to get IDEA running on NixOS? Mine gets stuck after the splash screen.

      export _JAVA_AWT_WM_NONREPARENTING=1

Oh, sweet! That's a neat trick I haven't seen before. Yeah, seems importing it via NUR works 🎉

Yeah, about IDEA: I don't know why, but it doesn't. I see the splash screen with the version etc. It then draws a window, but the window is empty. I'll attach a screenshot to demonstrate. There is an error that appears in the console, though:

I don't really know what it's about, though.

Based on their docs, that's ~/.config/JetBrains/<...>, right?

Deleting that folder and launching idea-ultimate again gives this:

And the same blank window.
