Spring源码下载、构建

1.本文前期准备：

（1）Spring版本：spring-framework-5.0.2.RELEASE

　下载spring-framework-5.0.2.RELEASE后，在文件夹里找到build.gradle文件，可以查看对应的gradle版本。尽量对应下载gradle版本，以免依赖下载或者其他问题出现。

（2）gradle版本： gradle-4.3.1

　解压后配置环境变量。

2.构建

spring-framework-5.0.2.RELEASE文件夹下，打开cmd，执行gradlew.bat。

3.构建问题

D:\github\spring-framework-5.0.2.RELEASE>gradlew.bat

移动网络问题，要注释掉国外源。

修改build.gradle文件，添加阿里云仓库地址

buildscript {
    repositories {
        maven { url "https://maven.aliyun.com/nexus/content/groups/public/" }
        maven { url "https://maven.aliyun.com/nexus/content/repositories/jcenter" }
        maven { url "https://maven.aliyun.com/nexus/content/repositories/spring-plugin" }
        /* maven { url "https://repo.spring.io/plugins-release" } */
    }
    dependencies {
