Could not get resource ‘https://jcenter.bintray.com’

在看Netflix conductor源码时遇到的一个问题，记录一下。
由于conductor不是使用常规的maven，而是使用Gradle作为编译工具，并且其jar包仓库是jcenter，不是nexus或者mvnrepository。故而在编译项目时遇到这个报错（Stack Trace适当简略）：

Could not download commons-compress.jar (org.apache.commons:commons-compress:1.16)
      > Could not get resource 'https://jcenter.bintray.com/org/apache/commons/commons-compress/1.16/commons-compress-1.16.jar'.
         > Could not GET 'https://d29vzk4ow07wi7.cloudfront.net/commons-compress-1.16.jar'.

​​参考​​​ 找到项目的​​build.gradle​​文件的节点​​*.repositories​​：

buildscript {
    repositories {
        // 注释，并添加下面一行
        // jcenter()
        maven { url "http://jcenter.bintray.com" }        
    }
}
allprojects {
    repositories {
        // 默认的jcenter是https协议的，也就是说把https换成http，遇到其他类似的问题，都可以这般尝试
        // jcenter()
        maven { url "http://jcenter.bintray.com" }
    }
}

但是​​gradle-wrapper.properties​​​文件不能修改为​​https​​​为​​http​​​：
​​​distributionUrl=https\://services.gradle.org/distributions/gradle-5.1.1-all.zip​​

Could not get resource ‘https://plugins.gradle.org/m2’

下载插件失败：

org.gradle.api.resources.ResourceException: Could not get resource 'https://plugins.gradle.org/m2/org/apache/maven/maven-ant-tasks/2.1.3/maven-ant-tasks-2.1.3.jar'.
Caused by: org.gradle.internal.resource.transport.http.HttpRequestException: Could not GET 'https://d29vzk4ow07wi7.cloudfront.net/maven-ant-tasks-2.1.3.jar
Caused by: java.net.SocketException: Software caused connection abort: recv failed

解决方法​​参考​​​：
在​​​settings.gradle​​文件最顶部添加如下配置：

pluginManagement {
    repositories {
        maven {
            url 'http://maven.aliyun.com/repository/gradle-plugin'
        }
        gradlePluginPortal()
    }
}
