title: Configure javascript code coverage with sonar
body: <p>How to configure sonar for my javascript project. I want to know about the code coverage and am using ant. Sonar version 2.13 &amp; javascript plugin of version 1.0. 
  And this is my build.xml</p>
  
  <pre><code>&lt;taskdef uri="antlib:org.sonar.ant" resource="org/sonar/ant/antlib.xml"&gt;
  &lt;classpath path="${lib.dir}/sonar/sonar-ant-task-1.3.jar"/&gt;
  &lt;/taskdef&gt;
  
  &lt;property name="sonar.jdbc.url"
        value="jdbc:mysql://xxx:3306/sonar?useUnicode=true&amp;amp;characterEncoding=utf8"/&gt;
  &lt;property name="sonar.jdbc.driverClassName" value="com.mysql.jdbc.Driver"/&gt; 
  &lt;property name="sonar.jdbc.username" value="sonar"/&gt;
  &lt;property name="sonar.jdbc.password" value="sonar"/&gt;
  
  &lt;property name="sonar.host.url" value="xxx"/&gt;
  
  &lt;target name="sonar"&gt;
  &lt;property name="sonar.sources" value="$${webdir}"/&gt;
  
  &lt;property name="sonar.projectName" value="Project Name"/&gt;
  &lt;property name="sonar.language" value="js"/&gt;
  &lt;property name="sonar.tests" value="${test.dir}"/&gt;
  
  &lt;sonar:sonar key="org.gap.commerce:services" version="0.1"xmlns:sonar="antlib:org.sonar.ant"/&gt;       
  &lt;/target&gt;
  </code></pre>
