Current behavior:

$ ls -l ~/tmp/fcrepo_wrapper/
total 47M
-rw-r--r-- 1 dlweber users 47M May  5 13:04 fcrepo-webapp-4.7.1-jetty-console.jar

$ cat ~/.fcrepo_wrapper 
download_dir: /users/dlweber/tmp/fcrepo_wrapper

$ cat .fcrepo_wrapper 
port: 8984

$ fcrepo_wrapper clean

    def clean!
      stop
      remove_instance_dir!
      FileUtils.remove_entry(config.download_path) if File.exists?(config.download_path)
      FileUtils.remove_entry(config.tmp_save_dir, true) if File.exists? config.tmp_save_dir
      md5.clean!
      FileUtils.remove_entry(config.version_file) if File.exists? config.version_file
  end

change to:

    def clean!
      stop
      remove_instance_dir!
      FileUtils.remove_entry(config.tmp_save_dir, true) if File.exists? config.tmp_save_dir
      md5.clean!
      FileUtils.remove_entry(config.version_file) if File.exists? config.version_file
  end
