最近在看spring boot ，发现好多是spring中的技术或概念，于是找了一本书《Spring源码深度解析.pdf》,开始学习下源码是从git上下的，先把https://github.com/spring-projects/spring-framework  克隆成我的项目，然后为了节省时间，下载zip的方式下载到本地，接下来就是导入到开发工具eclipse了，

在cmd执行：gradle cleanidea eclipse时，报如下错误：

在这篇文章中找到，需要修改maven仓库：https://www.oschina.net/question/2380402_2181441

修改maven仓库

repositories { maven { url “http://repo.springsource.org/plugins-release” } }

以为是要修改maven的配置文件，结果找了半天，在https://blog.csdn.net/javandroid/article/details/75094335?locationNum=1&fps=1文章中发现是要修改项目下的build.gradle文件，

修改之

找到目录下的文件

打开文件修改。

修改完文件，保存，再执行命令，则发现构建成功，

在观察spring-tx目录下就变成eclipse可以导入的带.project和.classpath文件的项目目录了。

导入eclipse，剩下的项目感叹号❗的问题就继续阅读pdf解决吧。
