From https://github.com/senny/emacs-eclim

Install emacs-eclim. You have two options:

• Installation from the MELPA package archive.

  Just add the archive to package-archives if you haven't already, and

then install emacs-eclim with the package-install command.

• Manual installation from GitHub.

  (git clone git://github.com/senny/emacs-eclim.git)

  Add (add-to-list 'load-path "/path/to/emacs-eclim/") to your startup script.

I followed the first option, by

1. adding to ~/.emacs.d/init.el:

   (setq package-archives '(("gnu" . "http://elpa.gnu.org/packages/") ("marmalade" . "http://marmalade-repo.org/packages/") ("melpa" . "http://melpa.milkbox.net/packages/"))) 

2. then M-x package-install RET and Install package: emacs-eclim [No Match]. Why is there no match?

Thanks.
