title: Android studio 3.2.1 ArtifactResolveException: Could not resolve all artifacts for configuration ':classpath'
body: <p>After I update Android Studio to 3.2.1 and gradle version in my project I am getting following build error.</p>
  
  <p>I have already checked lots of questions related this question but no luck.</p>
  
  <p><strong>Project dependency Build.gradle</strong></p>
  
  <pre><code>buildscript {
  
      repositories {
          google()
          mavenCentral()
          maven { url 'https://maven.google.com' }
          gradlePluginPortal()
          jcenter()
      }
      dependencies {
          classpath 'com.android.tools.build:gradle:3.2.1'
  
          // NOTE: Do not place your application dependencies here; they belong
          // in the individual module build.gradle files
      }
  }
  
  allprojects {
      repositories {
          google()
          maven { url "https://jitpack.io" }
          jcenter ()
  
      }
  }
