Maven 2 Mirror的陷阱

Maven 2的安装和使用虽然不是一点即用，但也不是很复杂。然而，这两天我新装Maven，刚刚过了mvn -version，尝试create maven project就出问题了。问题详情如下。

D:/mavenSample>mvn archetype:create -DgroupId=com.mycompany.app -DartifactId=my-app

开始以为是internet 代理设置有问题。网上也有帖子这么说。可是换到ADSL后，不用代理了，问题仍然存在。

几经周折后发现，原因在于我画蛇添足多加了几个镜像，其中有的镜像没有同步更新maven库。经过测试，如下maven 镜像工作正常：

ibiblio.org
ibiblio Mirror of http://repo1.maven.org/maven2/
http://mirrors.ibiblio.org/pub/mirrors/maven2
central



redv.com

ibiblio.net

而下面的Maven镜像都有问题。
