Rachel, thanks again for weighing in. I'm a little confused and was hoping
to ask you for clarification. Earlier in this thread, you use a File
approach and it seemed to work. Why did you mention in the follow-up
comment that it doesn't actually work? Why did it work the first time, but
not the second time? Was it because in the first case you were using the
groovy command line interpreter, and in the second case that failed you
tried to run from inside a Groovy script, maybe? Or was it something else
I'm missing entirely?
