title: How do I resolve a plugin conflict in Eclipse?
body: <p>I'd like to upgrade my Helios installation of Eclipse to Indigo.  When I do, I get the following message:</p>
  
  <pre><code>Cannot complete the install because of a conflicting dependency.
    Software being installed: Eclipse IDE for Java EE Developers 1.4.2.20120213-0813 (epp.package.jee 1.4.2.20120213-0813)
    Software currently installed: Oracle GlassFish Server Tools 1.6.1.201009290929 (oracle.eclipse.tools.helios.glassfish.feature.group 1.6.1.201009290929)
  </code></pre>
  
  <p>So my first thought was to simply uninstall GlassFish.  For the life of me, I can't figure out how and where to go to do this.  I went to Help->About Eclipse...->Installation Details.  The only place that it looks like I can uninstall stuff is in the "Installed Software" tab.  I do not see the Oracle Glassfish package anywhere.  If I go to "Feature" or "Plug-ins", I can find it just fine, but there is no option to uninstall.</p>
  
  <p>So my next thought was to upgrade Glassfish.  So I put the indigo repo in there, but I still get the same message when trying to update.  Any ideas?</p>
