title: Gradle dependencies update
body: <p>One of the advantages of using Gradle in Android Studio is that it helps in dependency management. So if I have used a particular version of a library in my <code>build.gradle</code> file,
  then how will I force it to update the dependency version once the higher version is available?</p>
  
  <p>Some of the dependencies in my build.gradle are specified as</p>
  
  <pre><code>dependencies {
      compile project(':facebookSDK')
      compile files('libs/picasso-2.1.1.jar')
      compile files('libs/crouton-1.8.1.jar')
  }
  </code></pre>
