解决：在两个repositories中加上相应代码。

buildscript {
    allprojects {
        repositories {
            google()
            jcenter()
            mavenCentral()
        }
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.0.1'
    }
    repositories {
        jcenter()
        mavenCentral()
        google()
    }
}
