title: No reported language in a maven project
body: <p>I've been looking into the logs in the project I'm currently working on and trying to get rid of the warnings where most are related to missing versions, having dependencies duplicated, and one particular warning has me stumped:</p>
  
  <blockquote>
    <p>[INFO] --- maven-clover2-plugin:3.1.12.1:instrumentInternal (default)
    @ project-name ---</p>
    
    <p>[WARNING] The reported language of this project is none, attempting to
    instrument sources anyway</p>
    
    <p>[INFO] No Clover instrumentation done on source files
    in:[~/Projects/projectOne/moduleOne/src/main/java] as no matching
    sources files found (JAVA_LANGUAGE)</p>
  </blockquote>
  
  <p>As far I understand, clover needs a language to instrument sources. I followed this guide: <a href="https://confluence.atlassian.com/display/CLOVER031/Clover-for-Maven+2+and+3+User%27s+Guide" rel="nofollow">https://confluence.atlassian.com/display/CLOVER031/Clover-for-Maven+2+and+3+User%27s+Guide</a></p>
  
  <p>I also specified the JDK in the configuration of this plugin but without success.</p>
