title: Multiple maven repositories in Gradle
body: <p>I have the following build.gradle:</p>
  
  <pre><code>buildscript {
      repositories {
          maven { url 'https://maven.fabric.io/public' }
  
          maven {
              url "https://dl.bintray.com/fyber/maven"
          }
  
          maven {
              url "https://dl.bintray.com/supersonic/android-sdk"
          }
      }
  
      dependencies {
          classpath 'io.fabric.tools:gradle:1.19.1'
      }
  }
  apply plugin: 'com.android.application'
  apply plugin: 'io.fabric'
  apply plugin: 'com.google.gms.google-services'
  
  dependencies {
  // Ads
        compile 'com.supersonic.sdk:mediationsdk:6.1.0@jar'
  }
  </code></pre>
  
  <p>And I'm getting this error:</p>
  
  <blockquote>
    <p>Error:(88, 13) Failed to resolve:
    com.supersonic.sdk:mediationsdk:6.2.0</p>
  </blockquote>
  
  <p>I've checked that library exists in the repository. Why am I getting this error?</p>
