1、下载gradle

https://gradle.org/releases/

解压到磁盘

2、配置环境变量

GRADLE_HOME、PATH、GRADLE_USER_HOME【可以指向安装目录自己创建的.gradle文件夹】

PATH = %GRADLE_USER_HOME%\bin

maven本地仓库 --> 所有的jar包
自己在gradle-6.8.2创建一个gradle文件夹

记得在cmd使用gradle -version

3、配置下载加速

Gradle 还是从 maven 仓库下载的。
给gradle-6.8.2安装目录下init.d文件夹，放一个init.gradle文件，内容如下：

gradle.projectsLoaded {rootProject.allprojects {buildscript {repositories {def JCENTER_URL = 'https://maven.aliyun.com/repository/jcenter'def GOOGLE_URL = 'https://maven.aliyun.com/repository/google'def NEXUS_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://jcenter.bintray.com/')) {project.logger.lifecycle "Repository ${repo.url} replaced by $JCENTER_URL."println("buildscript ${repo.url} replaced by $JCENTER_URL.")remove repo}else if (url.startsWith('https://dl.google.com/dl/android/maven2/')) {project.logger.lifecycle "Repository ${repo.url} replaced by $GOOGLE_URL."println("buildscript ${repo.url} replaced by $GOOGLE_URL.")remove repo}else if (url.startsWith('https://repo1.maven.org/maven2')) {project.logger.lifecycle "Repository ${repo.url} replaced by $REPOSITORY_URL."println("buildscript ${repo.url} replaced by $REPOSITORY_URL.")remove repo}}}jcenter {url JCENTER_URL}google {url GOOGLE_URL}maven {url NEXUS_URL}}}repositories {def JCENTER_URL = 'https://maven.aliyun.com/repository/jcenter'def GOOGLE_URL = 'https://maven.aliyun.com/repository/google'def NEXUS_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://jcenter.bintray.com/')) {project.logger.lifecycle "Repository ${repo.url} replaced by $JCENTER_URL."println("buildscript ${repo.url} replaced by $JCENTER_URL.")remove repo}else if (url.startsWith('https://dl.google.com/dl/android/maven2/')) {project.logger.lifecycle "Repository ${repo.url} replaced by $GOOGLE_URL."println("buildscript ${repo.url} replaced by $GOOGLE_URL.")remove repo}else if (url.startsWith('https://repo1.maven.org/maven2')) {project.logger.lifecycle "Repository ${repo.url} replaced by $REPOSITORY_URL."println("buildscript ${repo.url} replaced by $REPOSITORY_URL.")remove repo}}}jcenter {url JCENTER_URL}google {url GOOGLE_URL}maven {url NEXUS_URL}}}
}

即可进行加速下载。

4、配置idea整合

相当于maven仓库

5、下载Spring源码

Spring在github上的仓库地址是：https://github.com/spring-projects/spring-framework
尽量不要下载最新版本(我下载最新版本失败了)
https://github.com/spring-projects/spring-framework/releases/tag/v5.3.5
版本号

gradle(尽量一致)

6、 导入Spring源码

Spring导入到总工程中。使用gradle导入。

使用我们的gradle，jdk是15版本

下载慢的话，就不要使用wifi，使用流量
成功
