Running remote selenium tests throws error: '[testng] Unknown option: -sourcedir' - ant

Question

I have a cluster of VM's (all Windows 7) that I am trying to use to run some continuous integration from Jenkins. The tests are written in Java and from my local environment (windows 7) I can remotely connect to a VM and run my tests without any problems.
When I schedule the tests to run in Jenkins, I use the same command line arguments but during execution I get:
...

My Jenkins instance runs on a different box (ubuntu). I just upgraded to Ant 1.8.2 on that box. Can this be a testng issue? I've seen this issue a few places but no concrete answers yet, any help is appreciated, thanks.

For some reason, Jenkins is passing "-sourcedir" to TestNG, which is not a recognized option.
