You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: tailwind_jit.rb
    path of file: ./repos/ruby-companies/plugins/builders
    
    the code of the file until where you have to start completion: class Builders::TailwindJit < SiteBuilder
  def build
    hook :site, :pre_reload do |_, paths|
      # Don't trigger refresh if it's a frontend-only change
      next if paths.length == 1 && paths.first.ends_with?("manifest.json")

      # Save out
    
  def build
    hook :site, :pre_reload do |_, paths|
      # Don't trigger refresh if it's a frontend-only change
      next if paths.length == 1 && paths.first.ends_with?("manifest.json")

      # Save out a comment file to trigger Tailwind's JIT
      refresh_file = site.in_root_dir("frontend", "styles", "jit-refresh.css")
      File.write refresh_file, "/* #{Time.now.to_i} */"
      throw :halt # don't continue the build, wait for watcher rebuild
    end
  end
end
