title: create POM with junit 4
body: <p>I use Maven 3.0.4 and want to have junit 4 by default. </p>
  
  <p>My projects are created with the command :<br>
  <b>$>mvn archetype:create -DgroupId=my.group.id -DartifactId=myArtifactId -DpackageName=my.package.name</b><br><br>
  This puts a depency to junit version 3.8.1 in the created pom.xml, dispite the fact that verion 4.8.1 is already present.<br>
  There are no dependencies to junit in my global settings.xml, and I haven't a local .m2/repository/settings.xml. I don't want to remove the old version 3.8.1., but want that all new projects are created with version 4.8.1<br><br>
  Can I do this in my settings.xml (global or local does not matter)? And if so what is the correct syntax?</p>
