title: Why am I getting NoClassDefFoundError on JSONObject in amazon-kinesis-client?
body: <p>I've incorporated the code from DynamoDB streams adapter demo from aws-dynamodb-examples, into my Maven project, and I'm getting a run-time error: </p>
  
  <pre><code>Exception in thread "Thread-2" java.lang.NoClassDefFoundError: com/amazonaws/util/json/JSONObject
  at com.amazonaws.services.kinesis.leases.impl.Lease.toString(Lease.java:229)
  </code></pre>
  
  <p>Any idea why this happens and what I can do to fix it?</p>
