1. 下载spring-framework源代码
访问spring-framework的Git地址：
https://github.com/spring-projects/spring-framework
源码下载URL：
https://github.com/spring-projects/spring-framework.git
git@github.com:spring-projects/spring-framework.git
2. 编译源码
2.1 下载Gradle工具及相关依赖
进入spring-framework下载目录，执行./gradlew
2.2 查看可编译的编译任务
按照指示，可以先查看编译任务有哪些，执行./gradlew tasks

2.3 执行spring的编译任务
上面罗列了很多任务，选择执行build任务，命令如下：./gradlew build
这步会编译整个工程，预计时间为一个多小时，保持网络通畅，就可以去干其他事情了
我这次编译花了53min，编译完成的截图：
2.4 执行导入eclipse的脚本
因为idea可以兼容eclipse的工程，故可以直接执行导入eclipse工程的初始化脚本，当然了，目前也只有eclipse的可用脚本
导入idea只有一个说明文档：import-into-idea.md
准备执行初始化，找到“import-into-eclipse” 的可执行脚本，Windows下是.bat，类Unix系统都是.sh
确认本地已经安装了Eclipse开发工具，因为执行这个脚本前需要安装Eclipse，安装完成后
执行命令：./import-into-eclipse.sh
已经安装了Eclipse，点击Enter键继续，开始第一步编译工具，生成各自工程的metadata文件
这步花费时间较长，我本地花费了14min
完成后，点击Enter继续，开始第二步工作，导入工程到Eclipse中
导入完成后，点击Enter继续，开始第三步工作，生成根目录下的metadata
点击Enter继续，开始第四步工作，重新导入工程到Eclipse中
至此编译完成并初始化Eclipse工程完成，第五步增加Git支持和分享
大功告成，Goodbye！
