我尝试使用REST API和wget：

wget --user=username --password=password http://<ip>:<port>/nexus/service/local/artifact/maven/content?g=<group>&a=<artifact>&v=<version>&r=snapshots

Resolving <ip stuff>
Connecting to <ipv6 stuff>... Failed: Connection refused.
Connecting to <ipv4 stuff>... connected.
HTTP request sent,awaiting response... 401 Unauthorized
Reusing existing connection to <ip>:<port>.
HTTP request sent,awaiting response... 400 Bad Request
2014-05-11 20:17:01 ERROR 400: Bad Request.

有谁知道,如何让这个工作？

编辑：我可以使用浏览器下载工件(并登录到web界面)
