vimPlugins.nvim-java: failed to install with error Alias lua-async-await is still in vim-plugins

[felissedano]

Nixpkgs version

• Unstable (25.05)

Describe the bug

I am trying to setup nvim-java plugin on neovim with nixCats. However, when I try to run home-manager switch --flake . it fails with error: Alias lua-async-await is still in vim-plugins. I then tried to install it directly in home-manager with home.packages and it shows me the same error. Removing the package or installing a different vim plugin and it works fine.

I searched up lua-async-await and it appears to be a vim plugin as well, which is packaged in the unstable channel without a maintainer. I try to install it out of curiosity and it also failed to install. I assume the problem is either in the nvim-java package or lua-async-await package.

Steps to reproduce

add vimPlugins.nvim-java in home.packages inside home.nix file
run home-manager switch --flake .

I am using unstable as an overlay, so for me it looks like:

home.packages = with pkgs; [
 ...
] ++ [unstable.pkgs.vimPlugins.nvim-java];

Expected behaviour

nvim-java plugin gets installed and does not throw error.
