title: Failed to apply plugin [id 'com.android.library']
body: <p>I try to compile a Android Project which uses another library called HoloGraphLibrary. But when I want to compile the following error occurs:</p>
  
  <p>Plugin is too old, please update to a more recent version, or set ANDROID_DAILY_OVERRIDE environment variable to "9e19705c8c53c2712ca27200bfa349e4757e2264"</p>
  
  <p>Error:(1, 1) A problem occurred evaluating project ':HoloGraphLibrary'.</p>
  
  <blockquote>
    <p>Failed to apply plugin [id 'com.android.library']
    Could not create plugin of type 'LibraryPlugin'.</p>
  </blockquote>
  
  <p>The source of that error is:</p>
  
  <pre><code>apply plugin: 'com.android.library'
  
  android {
      compileSdkVersion Integer.parseInt(project.ANDROID_BUILD_SDK_VERSION)
      buildToolsVersion project.ANDROID_BUILD_TOOLS_VERSION
  
      sourceSets {
          main {
              java.srcDirs = ['src']
              res.srcDirs = ['res']
              manifest.srcFile 'AndroidManifest.xml'
          }
      }
  }
  </code></pre>
  
  <p>which is the build.gradle of the library. The build.gradle of the app looks as follows:</p>
  
  <pre><code>apply plugin: 'com.android.application'
  
  android {
      compileSdkVersion 21
      buildToolsVersion '19.1.0'
      defaultConfig {
          applicationId "XXXXXXXXXXX"
          minSdkVersion 14
          targetSdkVersion 21
          versionCode 2
          versionName '1.0.1'
      }
  buildTypes {
      release {
          minifyEnabled true
          proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
      }
  }
  sourceSets {
      main {
          res.srcDirs = ['src/main/res', 'src/main/res/tut', 'src/main/res/tutorial']
          resources.srcDirs = ['src/main/resources', 'src/main/resources/te']
      }
  }
  }
  
  dependencies {
      compile fileTree(include: ['*.jar'], dir: 'libs')
      compile 'com.android.support:appcompat-v7:21.0.3'
      compile project(":HoloGraphLibrary")
  }
  </code></pre>
  
  <p>I just don't see how i can fix this. Any hints?</p>
  
  <p>Thank you</p>
  
  <p>--------------- EDIT ----------------</p>
  
  <p>This is the top level gradle 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:2.1.0-beta1'
  
          // NOTE: Do not place your application dependencies here; they belong
          // in the individual module build.gradle files
      }
  }
  
  allprojects {
      repositories {
          jcenter()
      }
  }
  </code></pre>
  
  <p>Unfortunately, the suggestion of G.K. did not work!</p>
  
  <p>I have even tried to set the ANDROID_DAILY_OVERRIDE variable to what it has said to, but again the same error.</p>
