title: How update plugins in android studio?
body: <p>I ran my android project after almost a week and I got this message:</p>
  
  <blockquote>
    <p>Plugin is too old, please update to a more recent version, or set
    ANDROID_DAILY_OVERRIDE environment variable to
    "a8faa180fc282060c9b8ec88f9bdcc9072121284"</p>
  </blockquote>
  
  <p><strong>How do I update my Plugins?</strong> I am using android Studio 2.0. Here is my build.gradle project file</p>
  
  <pre><code>// Top-level build file where you can add configuration options common to all sub-projects/modules.
  
  buildscript {
  repositories {
      jcenter()
  }
  dependencies {
      classpath 'com.android.tools.build:gradle:2.0.0-alpha1'
  
      // NOTE: Do not place your application dependencies here; they belong
      // in the individual module build.gradle files
  }
  }
  
  allprojects {
      repositories {
          jcenter()
      }
  }
  
  task clean(type: Delete) {
      delete rootProject.buildDir
  }
  </code></pre>
