[Java知识库]用IDEA搭建spring源码阅读环境

第一步、准备gradle环境

1、去官网下载gradle
https://gradle.org/releases/

2、将其解压缩，创建repository文件夹 和init.d文件夹

创建init.gradle文件
输入文本信息，主要是配置阿里云镜像仓库地址，和maven的类似

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
            }
        }
    }
}

3、为了方便，设置环境变量GRADLE_HOME 和GRADLE_USER_HOME(看后面的截图就明白会被idea使用)

GRADLE_HOME

gradle路径，例如：

D:\Program Files\gradle-6.8.3

第二步、下载spring源码

github下载源码比较慢，我们通过码云的方式将其下载下来。当然也可以直接从github的官网直接拉取下拉。

spring源码官网：https://github.com/spring-projects/spring-framework

以下是同步到码云的操作

确认后就可以同步完成了
由于从码云上拉取代码需要ssh校验

如果之前有弄过ssh-keygen -t rsa也就是在个人文件夹下有一个.ssh文件夹里面有一个公钥
如下，讲id_rsa.pub已文本打开，复制里面的内容。

然后我们就可以通过IDEA的get from version control
复制ssh的连接，然后粘贴到idea中，与github上的git操作一致

刷新以下gradle依赖，首次刷新会非常慢，如果遇到了错误提示，则根据错误提示进行处理。完成后就会像我这样。

完成上面操作后spring的源码环境就算完成了。
