title: mvn versions:set not updating child poms
body: <p>I did much research on this but could not resolve it so far.</p>
  
  <p>I've following structure,</p>
  
  <pre><code>root folder
  parent/pom.xml (parent pom)
  artifact1/pom.xml
  artifact2/pom.xml
  pom.xml (aggregator pom)
  
  root/pom.xml
  ------------
  
  &lt;parent&gt;
      &lt;groupId&gt;releasetest2&lt;/groupId&gt;
      &lt;artifactId&gt;root&lt;/artifactId&gt;
      &lt;version&gt;1.0.4&lt;/version&gt;
      &lt;relativePath&gt;parent&lt;/relativePath&gt;
  &lt;/parent&gt;
  
  &lt;artifactId&gt;aggregator&lt;/artifactId&gt;
  &lt;packaging&gt;pom&lt;/packaging&gt;
  
  
  artifact1/pom.xml
  -----------------
  
  &lt;parent&gt;
      &lt;groupId&gt;releasetest2&lt;/groupId&gt;
  &lt;artifactId&gt;root&lt;/artifactId&gt;
  &lt;version&gt;1.0.4&lt;/version&gt;
  &lt;relativePath&gt;../parent&lt;/relativePath&gt;
  &lt;/parent&gt;
  
  &lt;groupId&gt;releasetest&lt;/groupId&gt;
  &lt;artifactId&gt;artifact1&lt;/artifactId&gt;
  &lt;packaging&gt;jar&lt;/packaging&gt;
  
  
  artifact2/pom.xml
  -----------------
  
  &lt;parent&gt;
  &lt;groupId&gt;releasetest2&lt;/groupId&gt;
  &lt;artifactId&gt;root&lt;/artifactId&gt;
  &lt;version&gt;1.0.4&lt;/version&gt;
  &lt;relativePath&gt;../parent&lt;/relativePath&gt;
  &lt;/parent&gt;
  
  &lt;groupId&gt;releasetest&lt;/groupId&gt;
  &lt;artifactId&gt;artifact2&lt;/artifactId&gt;
  &lt;packaging&gt;jar&lt;/packaging&gt;
  
  
  parent/pom.xml
  --------------
  
  &lt;groupId&gt;releasetest2&lt;/groupId&gt;
  &lt;artifactId&gt;root&lt;/artifactId&gt;
  &lt;version&gt;1.0.4&lt;/version&gt;
  &lt;packaging&gt;pom&lt;/packaging&gt;
  
  &lt;properties&gt;
      &lt;MAIN.version&gt;${project.version}&lt;/MAIN.version&gt;
  &lt;/properties&gt;
  
  &lt;dependencyManagement&gt;
      &lt;dependencies&gt;
          &lt;dependency&gt;
                &lt;groupId&gt;releasetest&lt;/groupId&gt;
                &lt;artifactId&gt;artifact1&lt;/artifactId&gt;
              &lt;version&gt;${MAIN.version}&lt;/version&gt;
          &lt;/dependency&gt;
          &lt;dependency&gt;
              &lt;groupId&gt;releasetest&lt;/groupId&gt;
              &lt;artifactId&gt;artifact2&lt;/artifactId&gt;
              &lt;version&gt;${MAIN.version}&lt;/version&gt;
          &lt;/dependency&gt;
      &lt;/dependencies&gt;
  &lt;/dependencyManagement&gt;

  <p>When I use mvn versions:set while being  in parent folder it only updates the parent/pom.xml. I expected it to update root/pom.xml artifact1/pom.xml and artifact2/pom.xml</p>
  
  <p>Is there a way to resolve this?</p>
