title: opencover report generator run through command prompt but not through ccnet.config
body: <p>When I run opencover through the command prompt it generates a xml, then i run report generator and it creates the html documents in the correct folder, but when i force a build, these don't happen, is this the correct way to do it? this what's setup in my ccnet.config</p>
  
  <pre><code>  &lt;!-- Open Cover --&gt;
  &lt;tasks&gt;
    &lt;exec&gt;
      &lt;executable&gt;C:\Program Files (x86)\OpenCover\OpenCover.Console.exe&lt;/executable&gt;
      &lt;buildargs&gt;-target:"C:\Program Files (x86)\NUnit 2.6.2\bin\nunit-console.exe" -register:user -targetargs:"/nologo /noshadow \"C:\Users\username\Documents\Visual Studio 2010\Projects\WebCrawlerMVC\WebCrawlerMVC.Tests\bin\Debug\WebCrawlerMVC.Tests.dll" -filter:+[WebCrawlerMVC]* -output:coverage.xml &lt;/buildargs&gt;
    &lt;/exec&gt;
    &lt;!-- Report Generator --&gt;
    &lt;exec&gt;      
      &lt;executeable&gt;C:\Program Files (x86)\ReportGenerator\bin\ReportGenerator.exe&lt;/executeable&gt;
      &lt;buildargs&gt;-reports:"C:\Program Files (x86)\OpenCover\coverage.xml" -targetdir:"C:\Program Files (x86)\CruiseControl.NET\server\WebCrawlerMVC\Artifacts\Reports" -reporttypes:XML;HTML&lt;/buildargs&gt;
    &lt;/exec&gt;
  &lt;/tasks&gt;
