    minimal footprint by selecting the minimal set of jars. Typically it is
    best to use something like Maven to manage jars, however this tutorial
    uses an aggregate Jar that contains all of the Jetty classes in one Jar.
    You can manually download the aggregate <a class="link" href="http://central.maven.org/maven2/org/eclipse/jetty/aggregate/jetty-all/9.3.0.v20150612/jetty-all-9.3.0.v20150612-uber.jar" target="_top"><code class="filename">jetty-all.jar</code></a>

      reject/deny access to the repository from the <span class="command"><strong>wget</strong></span>
      command line tool (due to abusive use of the tool by some groups). The
      administrators of the central maven repository have stated that the
