title: Confluent Maven repository not working?
body: <p>I need to use the Confluent <code>kafka-avro-serializer</code> Maven artifact. From the <a href="http://docs.confluent.io/3.1.1/installation.html#maven-repository-for-jars" rel="noreferrer">official guide</a> I should add this repository to my Maven pom</p>
  
  <pre><code>&lt;repository&gt;
    &lt;id&gt;confluent&lt;/id&gt;
    &lt;url&gt;http://packages.confluent.io/maven/&lt;/url&gt;
  &lt;/repository&gt;
  </code></pre>
  
  <p>The problem is that the URL <a href="http://packages.confluent.io/maven/" rel="noreferrer">http://packages.confluent.io/maven/</a> seems to not work at the moment as I get the response below</p>
  
  <pre><code>&lt;Error&gt;
    &lt;Code&gt;NoSuchKey&lt;/Code&gt;
    &lt;Message&gt;The specified key does not exist.&lt;/Message&gt;
    &lt;Key&gt;maven/&lt;/Key&gt;
    &lt;RequestId&gt;15E287D11E5D4DFA&lt;/RequestId&gt;

    &lt;/HostId&gt;
  &lt;/Error&gt;
  </code></pre>
  
  <p>In fact Maven does not find the artifact </p>
  
  <pre><code>&lt;dependency&gt;
    &lt;groupId&gt;io.confluent&lt;/groupId&gt;
    &lt;artifactId&gt;kafka-avro-serializer&lt;/artifactId&gt;
    &lt;version&gt;3.1.1&lt;/version&gt;
  &lt;/dependency&gt;
  </code></pre>
  
  <p>Do you know what the problem could be?
  Thank you</p>
