# LSP Custom Packages/Command {#sec-languages-custom-lsp-packages}

In any of the `opt.languages.<language>.lsp.package` options you can provide
your own LSP package, or provide the command to launch the language server, as
a list of strings. You can use this to skip automatic installation of a language
server, and instead use the one found in your `$PATH` during runtime, for
example:

```nix
vim.languages.java = {
  lsp = {
    enable = true;
    # this expects jdt-language-server to be in your PATH
    # or in `vim.extraPackages`
    package = ["jdt-language-server" "-data" "~/.cache/jdtls/workspace"];
  };
}
```
