title: How can I update my plugin in android studio?
body: <p>I am building a golf score card app with android studio and last night before I shut down my laptop it was building fine, however, this morning when I run Android studio I got the error "Plugin is too old, please update to a more recent version, or set ANDROID_DAILY_OVERRIDE environment variable to "aed79d567e57792ed352e708d2b7ca891ff897c6"" and my app structure has also altered and there is no longer a manifest folder.....<a href="http://i.stack.imgur.com/7Ge6k.png" rel="nofollow">image of app structure``</a></p>
  
  <p>Below is my gradle file:</p>
  
  <pre><code>    apply plugin: 'com.android.application'
  
  android {
      compileSdkVersion 23
      buildToolsVersion "21.1.2"
  
      defaultConfig {
          applicationId "com.example.biko.golfstroke"
          minSdkVersion 8
          targetSdkVersion 23
          versionCode 1
          versionName "1.0"
      }
      buildTypes {
          release {
              minifyEnabled false
              proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
          }
      }
  }
  
  dependencies {
      compile fileTree(dir: 'libs', include: ['*.jar'])
      testCompile 'junit:junit:4.12'
      compile 'com.android.support:appcompat-v7:23.1.1'
  }
  </code></pre>
