[网络协议]AS解决阿里云的http或https的问题，Using insecure protocols with repositories without explicit opt-in

首先说表达一下，真的是太恶心了，网上说的很多的方法都是不靠谱的。

下面我展示我的绝招。

1、在C:\Users\XXX\.gradle的init.gradle文件中添加一行代码：allowInsecureProtocol = true（切记有等于号）

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 ${repo.url} replaced by $ALIYUN_REPOSITORY_URL."
                    remove repo
                }
                if (url.startsWith('https://jcenter.bintray.com/')) {
                    project.logger.lifecycle "Repository ${repo.url} replaced by $ALIYUN_JCENTER_URL."
                    remove repo
                }
            }
        }
        maven {
		    allowInsecureProtocol = true  //就是这一行
            url ALIYUN_REPOSITORY_URL
            url ALIYUN_JCENTER_URL
        }
    }
}

2、在项目的根目标下的build.gradle中修改：allowInsecureProtocol true（切记无等于号），此外将http改为https

buildscript {
    repositories {
        google()
        jcenter()
        mavenCentral()
        maven {
            allowInsecureProtocol true //就是这一行
            url "https://jitpack.io"
        }
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:4.2.1'
    }
}

allprojects {
    repositories {
        google()
        jcenter()
        mavenCentral()
        maven {
            allowInsecureProtocol true //就是这一行
            url 'https://maven.aliyun.com/nexus/content/groups/public/'
        }

    }
}

然后就是好好的等待问题重新构建
