title: For Firestore which Dependencies needs to be added, to write Java code?
body: <p>I am writing code to Listen Data-Change in Firestore DB using Java code.
  I have used maven to add below dependencies: </p>
  
  <ol>
  <li>com.google.cloud:google-cloud-firestore:0.32.0-beta</li>
  <li>com.google.firebase:firebase-admin:5.8.0</li>
  </ol>
  
  <p>But while writing code, I am not able to resolve below imports:</p>
  
  <ol>
  <li>com.google.cloud.firestore.DocumentChange</li>
  <li>com.google.cloud.firestore.DocumentChange.Type</li>
  <li>com.google.cloud.firestore.EventListener</li>
  <li>com.google.cloud.firestore.ListenerRegistration</li>
  </ol>
  
  <p>What needs to be done or which dependencies needs to be added?</p>
