Xcode 7 PluginLoading: Required plug-in compatibility UUID
<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>
