概述

当前 Spring Cloud Alibaba 的 2.1.0.RELEASE 版本基于 Spring Cloud Greenwich 开发，
Spring Cloud Alibaba 项目都是基于 Spring Cloud，而 Spring Cloud 项目又是基于 Spring Boot 进行开发，并且都是使用 Maven 做项目管理工具。在实际开发中，我们一般都会创建一个依赖管理项目作为 Maven 的 Parent 项目使用，这样做可以极大的方便我们对 Jar 包版本的统一管理。

构建流程

创建文件夹
在电脑上创建一个文件夹hello-spring-cloud-alibaba当做项目的根目录
用idea打开
用idea打开刚刚创建的文件夹

创建子模块
选择hello-spring-cloud-alibaba根目录鼠标右键
创建子模块hello-spring-cloud-alibaba-dependencies
pom.xml内容如下

parent：继承了 Spring Boot 的 Parent，表示我们是一个 Spring Boot 工程
package：pom，表示该项目仅当做依赖项目，没有具体的实现代码
spring-cloud-alibaba-dependencies：在 properties 配置中预定义了版本号为 2.1.0.RELEASE ，表示我们的 Spring Cloud Alibaba 对应的是 Spring Cloud Greenwich 版本
build：配置了项目所需的各种插件
repositories：配置项目下载依赖时的第三方库

依赖版本简介
项目的最新版本是 2.1.0.RELEASE
1.5.x 版本适用于 Spring Boot 1.5.x
2.0.x 版本适用于 Spring Boot 2.0.x
2.1.x 版本适用于 Spring Boot 2.1.x
