(Note: the issue might be solved by just .gitignoreing the /build directory)

Maybe this would help.

On fileutils.rb the method cp_r at line 463 would be rewriten as

  def cp_r(src, dest, preserve: nil, noop: nil, verbose: nil,
           dereference_root: true, remove_destination: nil)
    fu_output_message "cp -r#{preserve ? 'p' : ''}#{remove_destination ? ' --remove-destination' : ''} #{[src,dest].flatten.join ' '}" if verbose
    return if noop
    fu_each_src_dest(src, dest) do |s, d|
	  next if File.directory?(s) && ['.git', '.gitignore', '.mnogootexrc', '.latexmkrc'].include?(File.basename(s))
      copy_entry s, d, preserve, dereference_root, remove_destination
    end
  end
