title: Inheriting the version of an optional dependency
body: <p>My company has 3 Maven projects organized as follows:</p>
  <p>Project A depends on Project B.</p>
  <p>Project B depends on Project C. (Project B has set Project C as an Optional dependency in their POM)</p>
  <p>I am the owner of Project A. I would like to add Project C as a direct dependency in my POM. However, I do not want to be responsible for keeping the version of Project C up to date. Is there a way I can inherit the version of Project C specified in Project B's POM at all times?</p>
