title: Maven root pom.xml marked as red when importing existing project into eclipse
body: <p>When importing existing maven project into eclipse my root pom.xml is marked red. 
  when i select on the pom.xml the message reads :</p>
  
  <blockquote>
    <p>Can't import project XYZ from an existing workspace folder</p>
  </blockquote>
  
  <p>This only happens for the root pom.xml</p>
  
  <p>Eclipse in use: Luna Service Release 2 (4.4.2)
  Maven Integration for Eclipse 1.5.2.20150413-2215   </p>
  
  <p>I have tested with number of different maven projects and in different workspaces. </p>
  
  <p>Please note this worked before, I have been working on some tutorials and created number of Maven projects with same name and artifact Ids etc. I have deleted all the earlier projects, but could there still be some conflicts ? </p>
  
  <p>any suggestions will help</p>
