"git-lfs: command not found" when cloning

[kmaasrud]

I am trying to make a new formula for mdzk. I'm new to Homebrew formulas and Ruby, but this is what I've got right now:

class Mdzk < Formula
  homepage "https://mdzk-rs.github.io"
  version "0.4.2"
  license "MPL-2.0"
  url "https://github.com/mdzk-rs/mdzk.git", tag: "0.4.2"
  depends_on "git-lfs" => :build
  depends_on "rust" => :build

  def install
    system "cargo", "install", *std_cargo_args
  end

  test do
    system "mdzk", "init", "test_mdzk"
    assert_predicate testpath/"test_mdzk", :exist?
  end
end

As you can see, the cloning depends on Git LFS. I saw in an issue that simply putting depends_on "git-lfs" => :build like I've done, will work. However, when I'm running brew install --build-from-source mdzk, I get the following error:

git-lfs filter-process: git-lfs: command not found
fatal: the remote end hung up unexpectedly
Error: mdzk: Failed to download resource "mdzk"
Failure while executing; `git checkout -f 0.4.2 --` exited with 128. Here's the output:
git-lfs filter-process: git-lfs: command not found
fatal: the remote end hung up unexpectedly

So git-lfs was obviously not installed as a dependency. Has anyone got any idea on how I can solve this? Any help is very much appreciated 😄

Based on the latter part of the discussion in Homebrew/homebrew-core#30190, it doesn't look like just adding depends_on "git-lfs" => :build will work, unfortunately.

You might need to create your own custom download strategy to handle clones that need git-lfs.

Thank you for the help! I found a way to circumvent git cloning, so all is good 😄
