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): | |||
``` | |||
devShell = pkgs.mkShell { | |||
buildInputs = [ | |||
pkgs.gradle | |||
pkgs.jdk17 | |||
]; | |||
NIX_LD_LIBRARY_PATH = pkgs.lib.makeLibraryPath [ | |||
pkgs.stdenv.cc.cc | |||
pkgs.openssl | |||
]; | |||
NIX_LD = pkgs.lib.fileContents "${pkgs.stdenv.cc}/nix-support/dynamic-linker"; # this needs .direnv:use flake --impure | |||
}; | |||
``` | |||
The important lines are the two lines starting with "NIX_LD...". They will let nix-ld wrap the required, dynamically loaded libraries so that they are found when building the devShell. | |||
