title: FirebaseAuth class now missing "getCurrentUser()" method?
body: <p>Firebase used to work just fine yesterday, but I opened my project this morning just to find that the <code>FirebaseAuth</code> class now has no reference whatsoever to the <code>FirebaseUser</code> class. I cannot find the <code>getCurrentUser()</code> method.</p>
  
  <p>The <a href="https://firebase.google.com/docs/reference/android/com/google/firebase/auth/FirebaseAuth.html#getCurrentUser()" rel="nofollow noreferrer">Google doc still shows that it exists</a> in the class, though!</p>
  
  <p><a href="https://i.stack.imgur.com/j0Wk5.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/j0Wk5.png" alt="method removed?!"></a></p>
  
  <p>My <code>imports</code> in that class:</p>
  
  <pre><code>import com.google.firebase.auth.AuthCredential;
  import com.google.firebase.auth.AuthResult;
  import com.google.firebase.auth.FirebaseAuth;
  import com.google.firebase.auth.FirebaseUser;
  import com.google.firebase.auth.GetTokenResult;
  import com.google.firebase.auth.GoogleAuthProvider;
  </code></pre>
  
  <p>The <code>build.gradle</code>:</p>
  
  <pre><code>api 'com.google.firebase:firebase-auth:16.0.2'
  implementation 'com.firebaseui:firebase-ui-auth:4.1.0'
  implementation 'com.google.firebase:firebase-core:16.0.1'
  implementation 'com.google.android.gms:play-services-auth:15.0.1'
  implementation 'com.google.firebase:firebase-admin:6.3.0'
  </code></pre>
  
  <p>And yes:</p>
  
  <ul>
  <li>I have <code>apply plugin: 'com.google.gms.google-services'</code> in my <code>build.gradle</code></li>
  <li>My app's <code>build.gradle</code> has <code>repositories { google() jcenter() }</code> in it</li>
  <li>I have <code>Clean</code> my project without getting errors</li>
  <li>I have restarted <code>AndroidStudio</code></li>
  </ul>
  
  <p>Current errors in my app (seem to have appeared out of nowhere since yesterday):</p>
  
  <ul>
  <li>The <code>getCurrentUser()</code> method doesn't exist anymore in my <code>FirebaseAuth</code> class (which is imported). Same for its <code>signInWithCredential(...)</code>, <code>signOut()</code>, <code>createUserWithEmailAndPassword(...)</code> and <code>signInWithEmailAndPassword(...)</code> methods.</li>
  <li>The <code>isEmailVerified()</code> method doesn't exist anymore in my <code>FirebaseUser</code> class anymore </li>
  <li>When trying to <code>Make Project</code>, I get this error: <code>Annotation processors must be explicitly declared now.  The following dependencies on the compile classpath are found to contain annotation processor.  Please add them to the annotationProcessor configuration. - auto-value-1.4.jar (com.google.auto.value:auto-value:1.4)
  Alternatively, set android.defaultConfig.javaCompileOptions.annotationProcessorOptions.includeCompileClasspath = true to continue with previous behavior.  Note that this option is deprecated and will be removed in the future. See https://developer.android.com/r/tools/annotation-processor-error-message.html for more details.</code>.</li>
  <li><code>build.gradle</code>'s <code>implementation 'com.android.support:appcompat-v7:27.1.1'</code> is now highlighted as an error (<code>All com.android.support librairies must have the same version specification</code>)</li>
