This bug report is for the latest version in the CVS, I dont know if it is a
know issue but im posting it anyhow. so it isnt forgotten.

I create a new project just to test the latest batch plugin, and configured a
task to do "dir". Then I tried to run the task, and I got the following
exception in the Executor#0

Steps to reproduce:
