Android Studio錯誤：類android.support.v4.hardware.display.DisplayManagerCompat已被添加到輸出。請刪除重複的副本

Question

我對着試圖建立我使用過Android Studio

Error:Class android.support.v4.hardware.display.DisplayManagerCompat has already been added to output. Please remove duplicate copies. 

我嘗試了不同的建議，這裏在計算器上，例如不包括像下面的包，但它仍然是相同的Android項目時，以下情況除外：

dependencies { 
    dependencies { 
     //compile project(':android-beacon-library') 
     compile 'org.altbeacon:android-beacon-library:2+@aar' 
     compile 'com.squareup.okhttp:okhttp:2.1.0' 
     compile ('com.squareup.picasso:picasso:2.2.0') { 
      exclude group: 'android.support', module: 'library' 
     } 
     compile 'com.google.code.gson:gson:2.2.4' 
     compile('com.github.Comcast:FreeFlow:v-0.6') { 
      exclude group: 'android.support', module: 'library' 
     } 
    } 
} 

使用gradlew.bat命令我試圖找到重複的條目，但該命令的輸出它不存在，粘貼下面是gradlew.bat :app:dependencies輸出：

餵你添加到你的gradle文件。它爲我工作得很好。希望它能幫助你！ :)

compile ('com.android.support:palette-v7:21.0.0'){ 
    exclude module: 'support-v4' 
}
