这是android studio屏幕截图，如果有帮助的话！

这是我的应用级别 build.gradle 文件：

This is my app level build.gradle file:

apply plugin: 'com.android.application'

repositories {
    mavenLocal()
    mavenCentral()
    flatDir {
        dirs 'libs'
    }
}

    compile 'com.facebook.android:facebook-android-sdk:[4,5)'
    //facebook
}

apply plugin: 'com.google.gms.google-services'

这是我的项目级别 build.gradle 文件：

And this is my project level build.gradle file:

buildscript {
    repositories {
        jcenter()
        mavenLocal()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:2.2.2'
        classpath 'com.google.gms:google-services:3.0.0'


        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        jcenter()
        mavenLocal()
    }
}

task clean(type: Delete) {
    delete rootProject.buildDir
}

为什么我突然开始出现这些错误。

提前谢谢！

Why I am starting to get these errors suddenly.
Thanks in advance!
