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: working_directory.rb
    path of file: ./repos/hyrax/app/services/hyrax
    
    the code of the file until where you have to start completion: # frozen_string_literal: true
module Hyrax
  # @deprecated Use JobIoWrapper instead
  class WorkingDirectory
    class << self
      # @deprecated No longer used anywhere in Hyrax code, naively assumes filenames of versions/revisions are distinct
      # Returns the file passed as filepath if that file exists
    
      def find_or_retrieve(repository_file_id, id, filepath = nil)
        Deprecation.warn("Hyrax::WorkingDirectory.find_or_retrieve() is deprecated and no longer used in Hyrax")
        return filepath if filepath && File.exist?(filepath)
        repository_file = Hydra::PCDM::File.find(repository_file_id)
        working_path = full_filename(id, repository_file.original_name)
        if File.exist?(working_path)
          Hyrax.logger.debug "#{repository_file.original_name} already exists in the working directory at #{working_path}"
          return working_path
        end
