title: Eclipse Repositories fail "Unable to read repository at"
body: <p>I generally don't use Eclipse, so perhaps I'm doing something wrong, but I've spent several hours going over this and can't find a problem.</p>
  
  <p>I needed a plugin for Eclipse (PigEditor or PigPen) and attempted to install it via repository, this failed with the error below. When it wouldn't install, I downloaded the .zip version, extracted the archive, found the folder containing features and plugins directory and tried installing it. This also failed. I also tried a PigPen .jar and it wasn't picked up at all when placing it into the plugins folder.</p>
  
  <p>I noticed along the way that I received a bunch of error messages where it looked like Eclipse was trying to fetch dependencies. For example...</p>
  
  <pre><code>Error
  Unable to read repository at http://download.eclipse.org/eclipse/updates/4.3.
  java.io.IOException: http://download.eclipse.org/eclipse/updates/4.3 is not a valid repository location.
  </code></pre>
  
  <p>That -should- be a valid repository location, it's listed about halfway down <a href="http://wiki.eclipse.org/Eclipse_Project_Update_Sites" rel="noreferrer">here</a>. This unable to read repository is the same error that I got when trying to install the previous plugin from repository. </p>
  
  <p>I then went to the Preferences -> Available Software Sites and tried all of the default installed repositories. There were 2 checked (the one listed above, and <a href="http://download.eclipse.org/releases/kepler" rel="noreferrer">http://download.eclipse.org/releases/kepler</a>) and 2 unchecked (<a href="http://download.eclipse.org/egit/updates" rel="noreferrer">http://download.eclipse.org/egit/updates</a> and <a href="http://www.eclipse.org/modeling/updates" rel="noreferrer">http://www.eclipse.org/modeling/updates</a>). I hit reload on any of those and receive the same error message as above.</p>
  
  <p>I can access websites from the internal browser. I've also tried changing my Network Connections preference to "Direct". </p>
  
  <p>Really all I care about is getting a working Pig plugin, so I'll accept that as an answer. I'm getting the feeling though that my failure to get any repositories is a symptom of a bigger problem (and I really want to know what's going on), so if you have troubleshooting steps I'm willing to try anything.</p>
