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: inject.rb
    path of file: ./repos/ruby/lib/bundler/cli
    
    the code of the file until where you have to start completion: # frozen_string_literal: true

module Bundler
  class CLI::Inject
    attr_reader :options, :name, :version, :group, :source, :gems
    def initialize(options, name, version)
      @options = options
      @name = name
      @version = version || last_version_number
      @group = options[:group].split(",") unless options[:group].nil?
      @source = options[:source]
      @gems = []
    end

    def run
      # The required arguments allow Thor to give useful feedback when the arguments
      # are incorrect. This adds those first two arguments onto the list as a whole.
      gems.unshift(source).unshift(group).unshift(version).unshift(name)

      # Build an array of Dependency objects out of the arguments
      deps = []
      # when `inject` support addition of more than one gem, then this loop will
      # help. Currently this loop is running once.
