NullPointerException with testng

Hi
I am trying to set up team city to run our build-script which launches our
testng tests.
However I have no luck doing so.

I have configured a dummy project to figure out this problem, but I'm still
stuck.

The ant script is roughly like this, and works command-line using ant, and
from within IntelliJ IDEA
]]>

I have set up TeamCity to check out this project and run the 'test' target.
But then I get this error message

What could be the problem?
