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 aks...@lap7:~$ dig repo1.maven.org. ; <<>> DiG 9.4.2-P2.1 <<>> repo1.maven.org. ;; global options: printcmd ;; Got answer: ;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 2732 ;; flags: qr rd ra; QUERY: 1, ANSWER: 1, AUTHORITY: 0, ADDITIONAL: 0 ;; QUESTION SECTION: ;repo1.maven.org.
