  <p>So I decided to update it. After click <code>update</code> in Android Studio <code>build.gradle</code> for a project opens. I change gradle version to 4.1 as suggested at pop up and click <code>synchronize</code> in Android Studio </p>
  
  <pre><code>classpath 'com.android.tools.build:gradle:4.1'
  </code></pre>
  
  <p>I see next error</p>
  
  <pre><code>Error:Could not find com.android.tools.build:gradle:4.1.  
  Searched in the following locations:
  file:/C:/Program Files/Android/Android Studio/gradle/m2repository/com/android/tools/build/gradle/4.1/gradle-4.1.pom
  file:/C:/Program Files/Android/Android Studio/gradle/m2repository/com/android/tools/build/gradle/4.1/gradle-4.1.jar
  https://jcenter.bintray.com/com/android/tools/build/gradle/4.1/gradle-4.1.pom

  https://dl.google.com/dl/android/maven2/com/android/tools/build/gradle/4.1/gradle-4.1.pom
  https://dl.google.com/dl/android/maven2/com/android/tools/build/gradle/4.1/gradle-4.1.jar
  </code></pre>
  
  <p>I checked <code>C:\Program Files\Android\Android Studio\gradle\m2repository\com\android\tools\build\gradle</code> and there is no <code>4.1</code> folder inside. 
  Do I need to install it manually? </p>
