解决问题：在你的gradle.properties（注意不是工程文件喽：指的是C:/Users/Administrator/.gradle夹中 MAC 电脑的本地的 gradle.properties 在用户目录下 .gradle 文件夹中）文件中把 如下配置去掉：
systemProp.http.proxyHost=127.0.0.1
systemProp.https.proxyPort=1087
systemProp.https.proxyHost=127.0.0.1
systemProp.http.proxyPort=1087

解决方法：
修改项目android/build.gradle
buildscript {
repositories {
// google()
// jcenter()
maven { url 'https://maven.aliyun.com/repository/google' }
maven { url 'https://maven.aliyun.com/repository/jcenter' }
maven { url 'http://maven.aliyun.com/nexus/content/groups/public' }
}
dependencies {
classpath 'com.android.tools.build:gradle:3.2.1'
}
}
allprojects {
repositories {
// google()
// jcenter()
maven { url 'https://maven.aliyun.com/repository/google' }
maven { url 'https://maven.aliyun.com/repository/jcenter' }
maven { url 'http://maven.aliyun.com/nexus/content/groups/public' }
