title: MavenFilteringException missing while executing org.apache.maven.plugins:maven-resources-plugin:2.6:resources
body: <p>I am getting below exception while compiling my project(on java6) with maven 3.2.5 and local repository and have all required jars downloaded.
  The project builds fine with maven2.0 and we are upgrading to 3.2.5. Have all required dependency jars downloaded, but it still complains with below error even when I see maven-filtering jar present in repository.</p>
  
  <p>Also, I tried below options but still the error is same. Is there any other place or setting I am missing here?</p>
  
  <ul>
  <li>copied maven-filtering 1.1 in repository-new\org\apache\maven\shared</li>
  <li>copied maven-filtering 3.1.1 in repository-new\org\apache\maven\shared </li>
  <li>cleaned up .m2 local cache </li>
  <li>copied maven-filtering 1.1 in repository-new\org\apache\maven\maven-filtering </li>
  <li>copied maven-filtering 3.1.1 in   repository-new\org\apache\maven\maven-filtering</li>
  </ul>
