title: Maven Dependency Plugin: usedDependency vs. ignoredUnusedDeclaredDependencies
body: <p>What is the difference between the <code>maven-dependency-plugin</code>'s <a href="https://maven.apache.org/plugins/maven-dependency-plugin/analyze-mojo.html#ignoredUnusedDeclaredDependencies" rel="nofollow noreferrer"><strong><code>ignoredUnusedDeclaredDependencies</code></strong></a> and <a href="https://maven.apache.org/plugins/maven-dependency-plugin/analyze-mojo.html#usedDependencies" rel="nofollow noreferrer"><strong><code>usedDependencies</code></strong></a>?</p>
  <p>I have several runtime/test-runtime dependencies that are flagged by the
  plugin as unused and declared and would like to ignore them. Both of these
  parameters seem to accomplish this.</p>
  <p>Can someone provide some clarification as to
  what the difference is between them, and which to use when?</p>
