title: Maven parent-child relationship
body: <p>I have encountered the below "<strong>pattern</strong>" for maven parent-child relationships:
  <img src="https://i.stack.imgur.com/rNOAU.png" alt="Relation ship example"><a href="http://yuml.me/3f8dd366" rel="noreferrer">http://yuml.me/3f8dd366</a></p>
  
  <p>In this example we have a module with 2 sub modules. The module has a parent pom "Parent for building the Module" which knows the two sub-modules as it's children.</p>
  
  <p>The sub-modules how ever have no idea that this parent knows them, and they think their parent is the one named "Parent for dependency management". Which has common configurations like dependency management, plugin configuration, common properties etc.</p>
  
  <p><strong>My question:</strong><br>
  Is this a "good" pattern? Meaning does it have advantages/disadvantages as the seemingly more intuitive patter of child&lt;->parent relationship</p>
