title: Kafka streams API sample KStream cannot be resolved to a type
body: <p>I am working thru this Kafka streams tutorial </p>
  
  <p><a href="https://kafka.apache.org/0110/documentation/streams/tutorial" rel="noreferrer">https://kafka.apache.org/0110/documentation/streams/tutorial</a></p>
  
  <p>on a Centos 7 machine running JRE 8+ and Kafka 0.11.0.1</p>
  
  <p>This is the line that throws the compile error</p>
  
  <pre><code>KStream&lt;String, String&gt; source = builder.stream("streams-plaintext-input");
  </code></pre>
  
  <p>Trying to compile the LineSplit example I get a Java exception</p>
  
  <pre><code>KStream cannot be resolved to a type
  </code></pre>
  
  <p>Being a Java noob, I am not sure how to resolve this. Double checked import declarations and even copy-pasted the sample in vain. </p>
  
  <p>Any leads on how to resolve this highly appreciated. </p>
