title: Xcode 7 PluginLoading: Required plug-in compatibility UUID
body: <p>When I tried to build project from command line, I got the following message from xcodebuild:</p>
  
  <blockquote>
    <p>xcodebuild[10713:1209993] [MT] PluginLoading: Required plug-in
    compatibility UUID F41BD31E-2683-44B8-AE7F-5F09E919790E for plug-in at
    path '~/Library/Application
    Support/Developer/Shared/Xcode/Plug-ins/SparkInspectorXcodePlugin.xcplugin'
    not present in DVTPlugInCompatibilityUUIDs</p>
  </blockquote>
  
  <p>I installed Spark Inspector a year ago, and deleted it about 6 months ago.</p>
  
  <p>Is there a way to reset Xcode so that it doesn't know there is such a plugin.</p>
  
  <p>So far I have tried re-install Xcode, delete all the reference data. They didn't work.</p>
