我的项目运行良好，但直到有一天，我将项目上传到 github.我不知道这个问题是否与此有关，但是今天当我编译我的 android studio 项目时，它开始向我显示这 4 个可怕的错误.我已经尝试了大部分谷歌结果，但没有任何帮助！

My project was working very fine, but until one day, when I uploaded my project to github. I don't know if this issue is related to that but today when I compiled my android studio project, it started showing me these 4 horrible errors. I have tried most of the google results but no help!

如果有帮助，这是android studio屏幕截图！

这是我的应用级 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build.gradle文件:

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
}

为什么我突然开始遇到这些错误.
提前致谢！
