maven不再使用新内核

我对发生在我身上的事情有点失望。我不是maven专家(即我只是按照别人告诉我的那样键入mvn clean install),但当我在debian机器上安装新内核时,maven似乎不再工作了:

在新内核(2.6.32-trunk-amd64)上,它无法下载依赖项,并显示“网络不可访问”消息:

Project ID: null:cecilia:pom:2.2-SNAPSHOT

Reason: Cannot find parent: org.objectweb.fractal:parent for project: null:cecilia:pom:2.2-SNAPSHOT for project null:cecilia:pom:2.2-SNAPSHOT

当然,网络似乎完全可以到达,因为这是我遇到的网络问题。

mvn --version
