title: Inheriting from the Parent POM file
body: <p>I am trying to understand an instruction for inheritance from a root pom file to a mid level pom file. The instruction says:</p>
  
  <p>Define your parent pom file inheritance and groupid, artifactid (but not the version), from the mid level parents to the root pom file.</p>
  
  <p>Does this mean that I should not specify a version for my mid level poms, or do not specify the group id and artifact id for the mid level poms?</p>
