  <p>After this, navigated to <code>http://serverip:9090</code>.
  1. The above project is listed in the dashboard. But no issues are listed in dashboard. instead its showing 0.
  2. Project coverage is set to 0% since there is no directories with classes.</p>
  
  <p>Where am i going wrong.. ??</p>
  
  <p>Thanks in advance</p>
  
  <p>Note : 
  At the beginning i started with my real-time project for the analysis. after facing lot of issues, i started with a sample project. </p>
