搭建Spring 源码工程

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，这样可以避免自动在系统C盘用户目录下生成gradle文件及下载依赖】

3、配置下载加速（国外则可以忽略此步骤）

因为github下载的源码中maven仓库路径是国外地址，此处可更改为阿里云仓库，gradle编译时下载jar包速度会极大提升

Gradle还是从maven仓库下载的

给gradle安装目录下init.d文件夹，放一个init.gradle文件，内容如下：

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74

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

注意：这里有一个坑，此时idea会为源码项目创建工作空间，等待创建完成后会立即开始构建项目，我们不要着急构建项目，还需要在IDEA中为spring源码项目配置gradle和JDK，点击停止按钮打断构建；一定要使用自己本地的gradle，否则会自动去下载默认gradle。

 

5、下载Spring源码

Spring在github上的仓库地址：https://github.com/spring-projects/spring-framework

Spring在码云上的仓库地址：https://gitee.com/mirrors/spring-framework

 

6、将Spring源码导入idea

 

注意：下载仓库的过程中中断下载可能导致一些插件下载一半，但是重新下载钱必须清空本地仓库的文件，否则会自动跳过这个插件导致环境一致跑步下去。

7、构建Spring源码

7.1、Build（构建）

上一步配置完idea中的gradle后，点击确认会自动开始构建，当所有模块build完成后，提示finished表示成功

7.2、编译Spring-oxml模块

​ 为确保所有模块都构建成功，这里可以参考官方spring源码工程中的 import-into-idea.md文档描述：先编译spring-oxm模块

 

7.3、预编译 Spring-core

?

1	$ ./gradlew :spring-core:compileTestJava

 

至此，spring源码编译就成功了
