From the Emacs Eclim github page:

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.

If followed the first option and:

  1. Added the following package-archives to my ~/.emacs.d/init.el file:

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

  2. Then typed M-xpackage-install and hit RET and the following message poped up:

    Install package: emacs-eclim [No Match]

Why does this error pop up?

Thanks in advance.

Maybe refreshing package contents could help: try evaluating (package-refresh-contents) or typing M-xpackage-refresh-contents.

    Just type (package-refresh-contents) in the *scratch* buffer and, after the closing bracket, hit C-j.

    The default binding for evaluating is C-x C-e.

Just wanted to add my experience. I installed Emacs on my Mac via Homebrew and couldn't get it to find or list any packages from repositories other than the standard GNU ELPA, despite adding MELPA and MELPA Stable to my package-archives in my init.el (similar to above), and despite doing package-refresh-contents, restarting Emacs, rebooting my machine, etc.

I noticed status messages about using TLS as it was loading list-packages (although they all appeared to be successful), and checked my Homebrew Emacs install -- I hadn't installed with the with-gnutls option. I uninstalled Emacs and reinstalled, this time using with-gnutls, and this fixed the problem for me. So, for me, something like:

brew install emacs --with-cocoa --with-gnutls

    It turns out (perhaps unsurprisingly) that TLS is only required if you use the "https" version of the repository URL's, e.g., if you use ("melpa" . "https://melpa.org/packages/") you need TLS, but if you use ("melpa" . "http://melpa.org/packages/"), which also works, you don't.

To my experience, this failed to detect (and autocomplete) the package I wanted, given a correct setup if you have already installed the package. A way to check that your configuration is properly set up and working is to package-list-packages and manually search for the package you want to install.
