Android Studiode jcenter 停止服务，改用mavenCentral

新建项目build出现提示

// An highlighted block
Please remove usages of `jcenter()` Maven repository from your build scripts and migrate your build to other Maven repositories.
This repository is deprecated and it will be shut down in the future.
See http://developer.android.com/r/tools/jcenter-end-of-service for more information.
Currently detected usages in: root project 'hello', project ':app'

找到jcenter（）代码块，在gradle里的build.gradle里

// An highlighted block
allprojects {
    repositories {
        google()
        mavenCentral()
        jcenter() // Warning: this repository is going to shut down soon
    }

将jcenter()更改为maven（）

// An highlighted block
repositories {
        google()
        mavenCentral()
        maven { url 'https://kotlin.bintray.com/kotlinx' }
    }

不会再出现上述错误。
