Hi Oisin,
we will have to resolve this using your machine. I don't have access to a Mac at the moment and when
we tried this on another Mac (Bjorns) we were not able to reproduce it.
Could you try to run the attached build.xml file. Both from the command line and from Eclipse. I'm
just curious if regexps work in some settings and not in others and track down where the difference
might occur. Perhaps Buckminster does something wrong when we start the ant-runner.
The expected result from the run is a printout:
"My name is print.thou.self"
Regards,
Thomas Hallgren
