解决gradle依赖下载太慢的问题

Could not resolve 依赖问题

解决方法：

1.在本地硬盘的C:\Users\Lenovo.gradle下新建一个init.gradle的文件

内容为：

allprojects{
repositories {
def ALIYUN_REPOSITORY_URL = 'http://maven.aliyun.com/nexus/content/groups/public'
def ALIYUN_JCENTER_URL = 'http://maven.aliyun.com/nexus/content/repositories/jcenter'
all { ArtifactRepository repo ->
if(repo instanceof MavenArtifactRepository){
def url = repo.url.toString()
if (url.startsWith('https://repo1.maven.org/maven2')) {
project.logger.lifecycle "Repository ALIYUN_REPOSITORY_URL."
remove repo
}
if (url.startsWith('https://jcenter.bintray.com/')) {
project.logger.lifecycle "Repository ALIYUN_JCENTER_URL."
remove repo
}
}
}
maven {
url ALIYUN_REPOSITORY_URL
url ALIYUN_JCENTER_URL
}
}
}

然后在你的安卓项目里build.gradle文件

：

// Top-level build file where you can add configuration options common to all sub-projects/modules.
buildscript {
repositories {
maven { url 'http://maven.aliyun.com/nexus/content/groups/public/' }
maven { url 'http://maven.aliyun.com/nexus/content/repositories/jcenter' }
maven { url 'http://maven.aliyun.com/nexus/content/repositories/google' }
maven { url 'http://maven.aliyun.com/nexus/content/repositories/gradle-plugin' }
google()
jcenter()
}
dependencies {
classpath "com.android.tools.build:gradle:4.1.0-alpha01"

    // 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/' }
maven { url 'http://maven.aliyun.com/nexus/content/repositories/jcenter' }
maven { url 'http://maven.aliyun.com/nexus/content/repositories/google' }
maven { url 'http://maven.aliyun.com/nexus/content/repositories/gradle-plugin' }
google()
jcenter()

}

}

task clean(type: Delete) {
delete rootProject.buildDir
}
