安卓第一课：gradle仓库的导入

今天装好android studio，结果刚进入就报错了:

SSL peer shut down incorrectly

读注释发现原来是gradle下载文件不成功。果然，原来是vpn掉线了，上网查了查，原来国内都用阿里的仓库下载，而国外是直接从谷歌的maven仓库下载。

换仓库，直接在settings.gradle里改成：

pluginManagement {
    repositories {
        maven { url 'http://maven.aliyun.com/repositories/public/' }
        maven { url 'http://maven.aliyun.com/repositories/jcenter' }
        maven { url 'http://maven.aliyun.com/repositories/google' }
        maven { url 'http://maven.aliyun.com/repositories/gradle-plugin' }
        mavenLocal()
        mavenCentral()
    }
}
dependencyResolutionManagement {
    repositoriesMode.set(RepositoriesMode.FAIL_ON_PROJECT_REPOS)
    repositories {
        maven { url 'http://maven.aliyun.com/repositories/public/' }
        maven { url 'http://maven.aliyun.com/repositories/jcenter' }
        maven { url 'http://maven.aliyun.com/repositories/google' }
        maven { url 'http://maven.aliyun.com/repositories/gradle-plugin' }
        mavenLocal()
        mavenCentral()
    }
}
