百度上搜了一下 解决了。可惜不知道为什么

解决方法：在project的builde.gradle做如下操作分别加上google()

buildscript {

repositories {

google()

....

}

dependencies {

classpath 'com.android.tools.build:gradle:3.0.0'

// NOTE: Do not place your application dependencies here; they belong

// in the individual module build.gradle files

}

}

allprojects {

repositories {

google()

.....

}

}
