最近下载了SPRING3.1.4，发现只有SPRING相关的源码，没有其依赖的jar包。SPRING依赖的jar相当多，自己一个一个的下载比较费劲，就仔细阅读了SPRING下载说明，新版本的SPRING都不在包涵依赖jar包，可以通过maven工具下载依赖。
D:\workspace\test\trunk\src\test>mvn complie
1、最近在切换Maven Repository路径时，eclipse中遇到了ArtifactDescriptorException的问题，而且一下就是400多个error。
错误如下：

看上去是有什么东西无法下载，但工程各种Clean、重新导入、Update Dependency、package、eclipse:eclipse都无效，切换到老的Repository就没问题。去新的路径下看，对应的jar包也都在，又怀疑pom中有格式错误，各种调整也没有解决。
后来使用mvn命令行进行jar下载，问题得到解决。
