title: JaCoCo report looks correct but can not view source
body: <p>I am new to JaCoCo and trying to figure out why the html report that I am generating is not linked with my source.</p>
  
  <p>The coverage numbers look correct and I can browse down to each class and then each method but I can not see the source.  I have tried many different things inside the sourcefiles tag but nothing is working.  Has anyone else had this issue?  Here is a snippet of my ant script:</p>
  
  <p>...</p>
  
  <pre><code>   &lt;test name="test.fw.UITestSuite" todir="${logdir}"/&gt;
      &lt;/junit&gt;
      &lt;/jacoco:coverage&gt;
      &lt;fail if="TestFailed" status="1" message="UI junit test failure detected"/&gt;
      &lt;echo message="${src}"/&gt;
      &lt;jacoco:report&gt;                                
          &lt;executiondata&gt;
              &lt;file file="jacoco.exec"/&gt;
          &lt;/executiondata&gt;                            
          &lt;structure name="UI"&gt;
              &lt;classfiles&gt;
                  &lt;fileset dir="${build}/fw"/&gt;
              &lt;/classfiles&gt;
              &lt;sourcefiles encoding="UTF-8"&gt;
                  &lt;fileset dir="fw" includes="**./*.java"/&gt;
              &lt;/sourcefiles&gt;
          &lt;/structure&gt;                                
          &lt;html destdir="report"/&gt;                                
      &lt;/jacoco:report&gt;
  &lt;/target&gt;
