title: How to depend on multiple projects in a maven library?
body: <p>My project depends on an external library, which consists of a number of maven projects. </p>
  
  <ul>
  <li>Do I have to define each of the projects in the library to be a module in my project's parent pom.xml? Is there a way to define the library as a whole in my project without individually listing all the projects?</li>
  </ul>
  
  <p>My project directly depends on only one project in the library, but that project depends on other projects in the library. </p>
  
  <ul>
  <li>Do I need to define all the projects in the library in my project's dependencies?</li>
  </ul>
