Spring源码

1.源码下载

本文编译的Spring源码是v5.2.x版本，jdk1.8 ,gradle6.5.1 仅供参考。

用gitee从github上导入spring的源码，然后从gitee上下载源码

https://github.com/spring-projects/spring-framework

然后就可以从gitee上面Clone到本地

2.gradle下载以及安装（或者使用idea自带的，这步跳过）

1. 下载Gradle前，先到Spring源码目录 ，进入到：spring-framework-5.2.x\gradle\wrapper 查看gradle-wrapper.properties 文件，下图中，distributionUrl对应的则为当前Spring源码版本对应的Gradle版本。 (本次本人使用的是gradle6.5.1,也报错)
   ![gradle]

2. 配置Gradle下载地址： https://gradle.org/releases/
   配置Gradle环境变量一：
   变量名：GRADLE_USER
   变量值：D:\software\gradle-6.5.1 （这里是我本地的gradle路径）
   配置Gradle环境变量二：
   变量名：GRADLE_USER_HOME
   变量值：D:\gradle-repo （这里配置的是gradle的仓库地址）
   配置Gradle环境变量三，配置 Path：
   环境变量值：%GRADLE_USER%\bin

3. 校验
   

3.修改源码配置

1. 找到源码根目录 build.gradle 文件 （相当于maven的pom），找到repositories配置向，编辑修改镜像仓库配置
   

repositories {
			maven { url 'https://maven.aliyun.com/nexus/content/groups/public/' }
			maven { url 'https://maven.aliyun.com/nexus/content/repositories/jcenter'}
			mavenCentral()
			maven { url "https://repo.spring.io/libs-spring-framework-build" }
		}

2.找到源码根目录 settings.gradle 文件增加国内镜像

pluginManagement {
	repositories {
		maven { url 'https://maven.aliyun.com/repository/public' }
		maven { url 'https://repo.spring.io/plugins-release' }
		mavenCentral()
		gradlePluginPortal()
		maven { url "https://repo.spring.io/release" }
	}
}

4.源码编译

1.将项目导入idea
2.修改idea中gradle配置

注释 ：

1. Gradle user home 仓库地址，我给配置成了gradle安装地址，导致包下载到了安装目录，然后懒得改了
2. Use Gradle from 默认是项目使用的gradle，有由我安装的gradle跟spring默认需要的gradle版本不一致，导致编译报错，所以使用的默认的，参考：spring-framework-5.2.x\gradle\wrapper 查看gradle-wrapper.properties 文件

5.编译问题

配置完毕后，开始build项目，Gradle开始下载一些相关文件，下载完毕后会出现以下信息：

Deprecated Gradle features were used in this build, making it incompatible with Gradle 8.0.

You can use '--warning-mode all' to show the individual deprecation warnings and determine if they come from your own scripts or plugins.

解决Git报错

1.进入spring源码根目录下，打开终端执行以下命令

1. git init .
2. git add .
3. git commit -am '初始化提交'

2.提交完重新刷新构建
