rxjava 的未解决依赖项无法下载 rxjava.jar

Question

我从未使用过这个库。它无法正确同步，但我的互联网运行良好，可以下载该 .jar 文件

这是我的错误：

无法解析 ':app@debug/compileClasspath' 的依赖关系：无法下载 rxjava.jar (io.reactivex.rxjava2:rxjava:2.1.0)

这是我的 build.app gradle：

这是我的 build.project gradle

// Top-level build file where you can add configuration options common to all sub-projects/modules.

buildscript {

    repositories {
        google()
        jcenter()

    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.1.4'




        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
        classpath 'com.google.gms:google-services:4.1.0'
    }
}

allprojects {
    repositories {
        google()
