Installing the Latest Eclipse in Ubuntu
=======================================

Here's a short shell script to quickly install the latest Eclipse in Ubuntu, since the one in the repositories is about two years old. As a bonus, it also replaces the ugly Eclipse icon with a `nicer one by Shaun Smith <http://shaun.boyblack.co.za/blog/2009/05/18/a-nice-eclipse-icon/>`_. Based on `these instructions <http://devianture.wordpress.com/2010/04/10/installing-eclipse-on-ubuntu/>`_.

* Run the script, like this: ``bash <(wget -qO- https://gist.github.com/raw/1071034/install-eclipse.sh)``
* When prompted, find the URL of the Eclipse Linux gzipped tarball you want to install from `the Eclipse website <http://www.eclipse.org/downloads/>`_.

    * Note: The link that you want has text that looks like *[Australia] Australian Academic Research Network (http)* - right click this and choose *Copy Link Address* to get the URL the script wants.

* The script will install OpenJDK [#]_, download Eclipse, patch the icon so it looks less ugly, and put all of the right files in the right places.

.. [#] In my experience, Eclipse (particularly CDT) has been more stable under OpenJDK than the Sun JRE, even though Eclipse recommends it.
