用IDEA搭建spring原始碼閱讀環境

第一步、準備gradle環境

1、去官網下載gradle
https://gradle.org/releases/

2、將其解壓縮，創建repository檔案夾 和init.d檔案夾

創建init.gradle檔案
輸入文本資訊，主要是配置阿里云鏡像倉庫地址，和maven的類似

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、為了方便，設定環境變數GRADLE_HOME 和GRADLE_USER_HOME(看后面的截圖就明白會被idea使用)

GRADLE_HOME

gradle路徑，例如：

D:\Program Files\gradle-6.8.3

第二步、下載spring原始碼

github下載原始碼比較慢，我們通過碼云的方式將其下載下來，當然也可以直接從github的官網直接拉取下拉，

spring原始碼官網：https://github.com/spring-projects/spring-framework

以下是同步到碼云的操作

確認后就可以同步完成了
由于從碼云上拉取代碼需要ssh校驗

如果之前有弄過ssh-keygen -t rsa也就是在個人檔案夾下有一個.ssh檔案夾里面有一個公鑰
如下，講id_rsa.pub已文本打開，復制里面的內容，

然后我們就可以通過IDEA的get from version control
復制ssh的連接，然后粘貼到idea中，與github上的git操作一致

重繪以下gradle依賴，首次重繪會非常慢，如果遇到了錯誤提示，則根據錯誤提示進行處理，完成后就會像我這樣，

完成上面操作后spring的原始碼環境就算完成了，
