title: In Eclipse 4.4 RCP builds, "The service Plugin converter could not be acquired."
body: <p>We began getting the build errors below for our RCP applications after updating to the recent Eclipse 4.4 IDE <em>Eclipse for RCP and RAP developers</em>. These occurred on multiple Windows and Mac platforms, in a vanilla Eclipse IDE install with no additional plug-ins.</p>
  
  <pre><code>  generateFeature:
    [eclipse.generateFeature] The service Plugin converter could not be acquired.
    [eclipse.generateFeature] The service Plugin converter could not be acquired.
    [eclipse.generateFeature] The service Plugin converter could not be acquired.
    ... 
  </code></pre>
  
  <p>Builds in an Eclipse 4.3.2 IDE continue to succeed. The only thing that differs is the IDE. (The build is launched with "Run in the same JRE as the workspace", making the current IDE relevant.)</p>
  
  <p>Googling for "Plugin converter could not be acquired" resulted in two links, neither of which was particularly helpful.</p>
  
  <p>How can these errors be eliminated?</p>
