docs/编译 spring 源码.md

+1. 下载
+2. 安装 gradle，下载的版本最好和 spring 源码中定义的一样，源码目录下 gradle/wrapper/gradle-wrapper.properties 中能看到 gradle 版本
+添加两个环境变量 GRADLE_HOME, GRADLE_USER_HOME
+3. 配置阿里云仓库地址，在配置的 GRADLE_USER_HOME 目录下创建 init.gradle 文件，内容：
+```gradle
+def repoConfig = {
+  all { ArtifactRepository repo ->
+      if (repo instanceof MavenArtifactRepository) {
+          def url = repo.url.toString()
+          if (url.contains('repo1.maven.org/maven2') || url.contains('jcenter.bintray.com')) {
+              println "gradle init: (${repo.name}: ${repo.url}) removed"
+              remove repo
+          }
+      }
+  }
+  // maven { url 'http://mirrors.cloud.tencent.com/nexus/repository/maven-public/' }
+  maven { url 'https://maven.aliyun.com/repository/central' }

+  allprojects {
+      buildscript {
+          repositories repoConfig
+      }
+      repositories repoConfig
+  }
+
+``` 
+
+4. 编译 gradlew :spring-oxm:compileTestJava
+5. 如果报错： Failed to calculate the value of task ':spring-core:compileJava21Java' property 'javaCompiler'，修改 spring-core 目录下的 spring-core.gradle 
+
+```
+multiRelease {
+	// targetVersions 17, 21
+	targetVersions 17
+}
+```
+
+注意，使用 jdk17 编译。
