Couldn't run mvn eclipse:eclipse on 5.12.1-SNAPSHOT

[gokceng1]

Hello,
I've followed the link http://docs.codehaus.org/display/ACT/Activiti+Designer+Developer+Guide but it seems I've misunderstood something.
I've downloaded eclipse-rcp-kepler-R-win32 with version platform 4.3. Maven is ok. Subversion is ok. I've imported projects to the eclipse I've downloaded as maven projects(Checkout as Maven Project). After that I've closed eclipse and opened cmd. I've run 'mvn clean eclipse:clean' on org.activiti.designer.parent. It runs without problem. But when I've run 'mvn eclipse:eclipse' command, it gives a failure message:

Also there are these two lines which confuse me:

[INFO] Adding repository http://download.eclipse.org/graphiti/updates/0.9.2
[INFO] Adding repository http://download.eclipse.org/graphiti/updates/0.9.2

Is there a problem here?

Seems an issue with maven cargo/http transfer… Maybe network/proxy-related?
