Description of issue

I created a Tap for my CLI app, but when I try to install it I get this error:

% brew install juraj-hrivnak/pakku/pakku
==> Tapping juraj-hrivnak/pakku
Cloning into '/usr/local/Homebrew/Library/Taps/juraj-hrivnak/homebrew-pakku'...

Tapped 1 formula (32 files, 12.5KB).
Error: juraj-hrivnak/pakku/pakku: wrong number of arguments (given 1, expected 0)

I don't know how to fix this problem. Installing the Formula locally from the pakku.rb works normally.

This is how the formula code looks like:

class Pakku < Formula
  desc "Multiplatform modpack manager for Minecraft: Java Edition"
  homepage "https://juraj-hrivnak.github.io/Pakku/"
  url "https://github.com/juraj-hrivnak/Pakku/releases/download/v0.8.7/Pakku-0.8.7.tar"
  hash "0dd7bfc7b48a319aad3d8ece3eb9e046cb0aefb00b1ecb10cc6800357ff30b20"
  license "EUPL-1.2"

  def install
    rm_f Dir["bin/*.bat"]
    libexec.install %w[bin lib]
    (bin/"pakku").write_env_script libexec/"bin/Pakku", Language::Java.overridable_java_home_env
  end

  test do
    assert_match "Could not read 'pakku-lock.json'", shell_output(bin/"pakku add jei", 1)
  end
end

Try replacing hash with sha256

Thanks! That was it.
