Setup groovy-emacs-mode without network connection

[perllb]

I need to use groovy-modes on a server which have no network connection, so I cannot use the

(require 'package)
(add-to-list 'package-archives
             '("melpa" . "https://melpa.org/packages/") t)
(package-initialize)

Or

(require 'package)
(add-to-list 'package-archives
             '("melpa-stable" . "https://stable.melpa.org/packages/") t)
(package-initialize)

in the .emacs file.

I tried to send the groovy-mode.el files and use that at startup, but does not work. Seems to be due to other dependencies needed, but cannot figure out which ones.

Is there a way I can setup groovy-modes without network?

Thanks for your help!
