Yes, it works for me so I need to get some more information.
A) does the maven build work locally for you ?
B) what is the exact error ? "failed to execute goal ..." could mean alot of things.
C) Are you using the examples we provide in central or is it your own war/ear project ?
D) Seam Web Project's aren't configured to work outofthebox on openshift so this would not be expected to work.
