查了网上说是jcenter()跑路了，所以不支持了；需要改用mavenCentral
所以在切换至Project找到build.gradle文件修改为下方，重新编译一下就OK了。

allprojects {
    repositories {
        google()
        mavenCentral()
        maven { url 'https://kotlin.bintray.com/kotlinx' }
//        jcenter() // Warning: this repository is going to shut down soon

    }
}
