2 Gradle下载失败
- 场景
首次使用Android Studio新建Andorid项目,Gradle下载相关组件时过慢或失败 - 方案
添加下载源,修改第一层文件夹下的build.gradle文件,添加maven{url ‘http://maven.aliyun.com/nexus/content/groups/public/’},完整问文件如下:
// 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/'}
google()
jcenter()
}
dependencies {
classpath "com.android.tools.build:gradle:4.0.1"
// 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
}
