title: Suppress Maven Dependency Plugin's "Unused declared dependencies found" warnings
body: <p>The <a href="http://maven.apache.org/components/plugins/maven-dependency-plugin/" rel="noreferrer"><code>maven-dependency-plugin</code></a> identifies what it believes to be unused dependencies when you compile by producing warnings at compile time.</p>
  
  <pre><code>[WARNING] Unused declared dependencies found:
  [WARNING]    org.foo:bar-api:jar:1.7.5:compile
  </code></pre>
  
  <p>In some cases this message is a false positive and the dependency is required transitively.</p>
  
  <p><strong>Question</strong>: How can I identify in my <code>pom.xml</code> that this is the case?</p>
