title: resource is not indexed in grails project and sonar
body: <p>I want to use sonar to monitor the junit test code coverage for a grails project. firstly I use grails code coverage plugin to generate the coverage.xml and configure sonar.groovy.cobertura.reportPath property, but there is no data in junit part. So I change the sonar.sources in the pom.xml from grails-app to grails-app/controllers,grails-app/services,grails-app/domain. then the junit code coverage appears but the console shows resource is not index.and the issues part in sonar dashboard becomes 0.  How can i solve that? thank you very much.
  sonarqube 4.5.1
  Groovy sonar plugin 1.0.1
  maven 3.2.5
  the pom configuration is below:</p>
  
  <pre><code>&lt;sonar.language&gt;grvy&lt;/sonar.language&gt;
  &lt;sonar.dynamicAnalysis&gt;reuseReports&lt;/sonar.dynamicAnalysis&gt;
  &lt;sonar.surefire.reportsPath&gt;test/reports&lt;/sonar.surefire.reportsPath&gt;
  &lt;sonar.groovy.cobertura.reportPath&gt;test/reports/cobertura/coverage.xml&lt;/sonar.groovy.cobertura.reportPath&gt;
  &lt;!--sonar.groovy.codenarc.reportPath&gt;test/CodeNarcReport.xml&lt;/sonar.groovy.codenarc.reportPath--&gt;
  &lt;sonar.sources&gt;src/groovy,src/java,grails-app/controllers,grails-app/services,grails-app/domain&lt;/sonar.sources&gt;
  </code></pre>
