title: Maven plugin for merging pom.xml files
body: <p>We have a parent Maven project (agregator) and some daughter projects:</p>
  
  <pre><code>parent/
    child1/
    child2/
    ...
  </code></pre>
  
  <p>Now we want convert that structure to one project and we need to merge pom.xml files together. The problem is that projects have very complicated pom.xml files with many configurations (lifecycle phases, platform specific settings, goals, etc..) and long lists of dependencies. Manual merging will be complicated and error-prone.</p>
  
  <p>Does someone know any Maven plugin for merging pom.xml files ?</p>
