Unable to install Eclim for Eclipse in Emacs

[aluva]

I did this:

$ sudo apt install eclipse eclipse-jdt

Then, tried to install eclim using use-package in Emacs:

(use-package eclim
      :ensure t
      :config
       (require 'eclim)
       (setq eclimd-autostart t)
       (defun my-java-mode-hook ()
       (eclim-mode t))
       (add-hook 'java-mode-hook 'my-java-mode-hook))

It seems, use-paclage did not install it though evaluation showed t. Then, I used terminal:

downloaded:

eclim_2.8.0.bin

debian# cd Downloads

`debian# ./eclim_2.8.0.bin`

Welcome to the installer for eclim 2.8.0.
Please specify the root directory of your eclipse install.
Ex: /opt/eclipse
/usr/local/eclipse

> `/home/tom/.eclipse/`

The eclipse launcher/executable could not be found in that directory

eclipse is installed in ~/.eclipse

(1) What is the root directory of eclipse install?

(2) Also, how to configure executable directory path, using use-package in Emacs?

(3) And, use-package shows that there is no emacs-eclim package in the repository!

(use-package emacs-eclim
   :ensure t)
