title: delete external library in Android Studio
body: <p>how can I delete an external library from Android Project using Android Studio ? In my gradle script I  have :</p>
  
  <pre><code>def neo4jVersion = "2.1.7"
  apply plugin: 'java'
  repositories {
     mavenCentral()
  }
  dependencies {
     compile "org.neo4j:neo4j:${neo4jVersion}"
  } 
  </code></pre>
  
  <p>This is pulling about 15 jars but I need to delete one of them, each time I do it, it deletes it but when I run the project again it reappears ! How to delete it permanently ? This is screenshot</p>
