Android gradle - 內容不允許在Prolog中

Question

我很難建立我的Android應用程序。我沒有添加任何依賴項，並試圖清理我的項目。仍然得到這個錯誤

Error:A problem occurred configuring project ':app'. 
> Could not resolve all dependencies for configuration ':app:_debugApkCopy'. 
    > Could not resolve com.android.support:animated-vector-drawable:25.0.0.

      > Content is not allowed in prolog. 

文件pom是空的。我不知道如何解決它。

謝謝
