Gradle设置阿里镜像_gradle 镜像

上一篇写到maven导包失败的解决方法，就联想到gradle中也遇到过这样的问题，导包download failed的情形。

解决方法参考了博客Could not download kotlin-compiler-embeddable.jar，采取方法二，Windows系统默认下载到：C:\Users(用户名).gradle，新建init.gradle

allprojects{
    repositories {
        def ALIYUN_REPOSITORY_URL = 'https://maven.aliyun.com/repository/central/'
        def ALIYUN_JCENTER_URL = 'https://maven.aliyun.com/repository/public/'
        all { ArtifactRepository repo ->
            if(repo instanceof MavenArtifactRepository){
                def url = repo.url.toString()
                if (url.startsWith('https://repo1.maven.org/maven2') || url.startsWith('http://repo1.maven.org/maven2')) {
                    project.logger.lifecycle "Repository ${repo.url} replaced by $ALIYUN_REPOSITORY_URL."
                    remove repo
                }
                if (url.startsWith('https://jcenter.bintray.com/') || url.startsWith('http://jcenter.bintray.com/')) {
                    project.logger.lifecycle "Repository ${repo.url} replaced by $ALIYUN_JCENTER_URL."
                    remove repo
                }
            }
        }
        maven {
            url ALIYUN_REPOSITORY_URL
            url ALIYUN_JCENTER_URL
			url 'https://maven.aliyun.com/repository/google/'
			url 'https://maven.aliyun.com/repository/gradle-plugin/'
        }
    }
 
 
    buildscript{
        repositories {
            def ALIYUN_REPOSITORY_URL = 'https://maven.aliyun.com/repository/central/'
            def ALIYUN_JCENTER_URL = 'https://maven.aliyun.com/repository/public/'
            all { ArtifactRepository repo ->
                if(repo instanceof MavenArtifactRepository){
                    def url = repo.url.toString()
                    if (url.startsWith('https://repo1.maven.org/maven2') || url.startsWith('http://repo1.maven.org/maven2')) {
                        project.logger.lifecycle "Repository ${repo.url} replaced by $ALIYUN_REPOSITORY_URL."
                        remove repo
                    }
                    if (url.startsWith('https://jcenter.bintray.com/') || url.startsWith('http://jcenter.bintray.com/')) {
                        project.logger.lifecycle "Repository ${repo.url} replaced by $ALIYUN_JCENTER_URL."
                        remove repo
                    }
                }
            }
            maven {
                url ALIYUN_REPOSITORY_URL
                url ALIYUN_JCENTER_URL
				url 'https://maven.aliyun.com/repository/google/'
				url 'https://maven.aliyun.com/repository/gradle-plugin/'
            }
        }
    }
}

但是在这样设置后也遇到过问题
因为kolin问题，将google改为了阿里云镜像，造成 Could not find aapt2-proto.jar (com.android.tools.build:aapt2-proto:0.3.1). 的问题，移除init.gradle即恢复正常。

所以在设置镜像时还是在所用项目中添加比较保险。
即在build.gradle中 两个repositories 添加
maven {url 'https://maven.aliyun.com/repository/public/';}
