How to update Eclipse from 2018-09 to 2018-12 : <p>I have Eclipse 2018-09.  My impressions was that Eclipse was moving to a rolling quarterly release, and by that I presumed I'd magically be offered updates every quarter to the newest.  But now that 2018-12 is out, my instance does not detect any new updates.</p>

<p>Looking at the update sites in Windows -> Preferences, Install/Update -> Available Software Sites (incompletely listed below), I notice they seemed to be pinned to specific versions:</p>

<ul>
<li><strong>The Eclipse Project Updates</strong>: <a href="http://download.eclipse.org/eclipse/updates/4.9" rel="noreferrer">http://download.eclipse.org/eclipse/updates/4.9</a></li>
<li><strong>The Eclipse Project Updates</strong>: <a href="http://download.eclipse.org/eclipse/updates/4.9/categories" rel="noreferrer">http://download.eclipse.org/eclipse/updates/4.9/categories</a></li>
<li><strong>Eclipse Project Repository for 2018-09</strong>: <a href="http://download.eclipse.org/eclipse/updates/4.9/R-4.9-201809060745" rel="noreferrer">http://download.eclipse.org/eclipse/updates/4.9/R-4.9-201809060745</a></li>
<li><strong>2018-09</strong>: <a href="http://download.eclipse.org/releases/2018-09" rel="noreferrer">http://download.eclipse.org/releases/2018-09</a></li>
<li><strong>Oracle Enterprise Pack for Eclipse 12.2.1.8 Dependencies</strong>: <a href="http://download.oracle.com/otn_software/oepe/12.2.1.8/oxygen/repository/dependencies/" rel="noreferrer">http://download.oracle.com/otn_software/oepe/12.2.1.8/oxygen/repository/dependencies/</a></li>
</ul>

<p>I've noticed there is also now <a href="https://www.eclipse.org/downloads/packages/installer" rel="noreferrer">an Eclipse Installer</a>, which says it is "The easiest way to install and update your Eclipse Development Environment.".  However, there is no description of updating, and when running it and pointing to the existing folder for 2018-09 (yes, I made a backup first to be safe), it does not update that folder but instead just creates a new sub-folder under the existing 2018-09 version called "eclipse" with presumably a complete copy of the new eclipse.  So that's a failed attempt.</p>

<p>What is the recommended way of upgrading from 2018-09 to 2018-12?  Is it:</p>

<ol>
<li>Manually download a new copy of Eclipse and spend hours configuring it to hopefully be almost the same as the configurations in 2018-09</li>
<li>Run the Eclipse installer in some other manner than I already have.</li>
<li>Manually updating the update sites (to what values?).  If the so, is there a way to specify to always use the latest on the update train?</li>
<li>Other?</li>
</ol>
