方法一:
使用开源中国的maven库:
阿里云的:http://maven.aliyun.com/nexus/content/groups/public/
在项目根目录下的build.gradle中添加如下:
方法1
buildscript {
    repositories {
        maven{url 'http://maven.aliyun.com/nexus/content/groups/public/'}
        google()
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.1.2'
        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}
allprojects {
    repositories {
        maven{url 'http://maven.aliyun.com/nexus/content/groups/public/'}
        google()
        jcenter()
    }
}
task clean(type: Delete) {
    delete rootProject.buildDir
}方法2
buildscript {
    repositories {
        google()
        jcenter(){
            url "http://maven.aliyun.com/nexus/content/groups/public/"
        }
        mavenCentral() // add repository
        
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.4.1'
        classpath 'com.jfrog.bintray.gradle:gradle-bintray-plugin:1.7.3'
        classpath 'com.github.dcendents:android-maven-gradle-plugin:2.1'
        //添加下面这行代码就OK了
        classpath 'com.novoda:bintray-release:0.6.1'
        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}
allprojects {
    repositories {
        google()
        jcenter(){url 'http://maven.aliyun.com/nexus/content/groups/public/'}
        
    }
}
task clean(type: Delete) {
    delete rootProject.buildDir
}
