Question

1. OS: macOS Catalina
2. 源代码地址：https://github.com/spring-projects/spring-framework/tree/4.1.x
3. 源代码分支：4.1.x
4. 源代码下载到本地后，根据文档 https://github.com/spring-projects/spring-framework/blob/4.1.x/import-into-idea.md 执行命令：./gradlew cleanIdea :spring-oxm:compileTestJava，报错如下：

$ ./gradlew cleanIdea :spring-oxm:compileTestJava

5. 看报错信息，大概明白从 https://repo.spring.io 下载依赖需要用户名、密码等认证信息。我应该怎么修改构建配置文件呢？

Answer 1

spring源码编译问题解决1，Received status code 401 from server问题，not found问题，更换阿里云镜像

Answer 2

如果只是看代码的话，直接切换到 a.b.c.RELEASE 的 tag 上，这样就不需要snapshot的依赖了
