Maven failed to resolve repo1.maven.org Inbo

scmuser created the topic: Maven failed to resolve repo1.maven.org Inbo
I installed Maven 2.2.1 on Ubuntu 8.04. When I first tried to run mvn it
didn’t work.
I have a direct connection to internet and I do not have firewall policies
which prohibit
internet access from any program (such as java.exe, as I found in one post)

Looking at the stack-trace it seems like the root of all evil is:

Caused by: java.net.UnknownHostException: repo1.maven.org

I tried to resolve it manually

akshay@lap7:~$ dig repo1.maven.org.

; <<>> DiG 9.4.2-P2.1 <<>> repo1.maven.org.
