title: Could not find org.apache.httpcomponents:httpclient:4.5.6 when adding Firebase Crashlytics
body: <p>I removed Fabrics Crashlytics to replace it with Firebase Crashlytics.</p>
  
  <p>I followed the steps mentioned here: <a href="https://firebase.google.com/docs/crashlytics/upgrade-sdk?platform=android" rel="nofollow noreferrer">https://firebase.google.com/docs/crashlytics/upgrade-sdk?platform=android</a></p>
  
  <p>I get the error:</p>
  
  <pre><code>Could not find org.apache.httpcomponents:httpclient:4.5.6.
  Searched in the following locations:
    - https://dl.google.com/dl/android/maven2/org/apache/httpcomponents/httpclient/4.5.6/httpclient-4.5.6.pom
  If the artifact you are trying to retrieve can be found in the repository but without metadata in 'Maven POM' format, you need to adjust the 'metadataSources { ... }' of the repository declaration.
  Required by:
      project :myProject &gt; com.google.firebase:firebase-crashlytics-gradle:2.1.1 &gt; com.google.firebase:firebase-crashlytics-buildtools:2.1.1
  </code></pre>
  
  <p>Do you see how to solve this problem? </p>
  
  <p>Thanks.</p>
