BUILD FAILED in 5s

解决办法：加上allproject.repositories 块，然后把仓库全都添加进去。

buildscript {
    repositories {
        google()
        mavenCentral()
        maven {  url 'https://jitpack.io'}
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:4.0.2'

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

allprojects {
    repositories {
        google()
        mavenCentral()
        maven {  url 'https://jitpack.io'}
    }
}
