testrunner.bat: syntax of command line incorrect

I am trying to run a SOAPUI opensource test suite via TeamCity. In TeamCity, there is a step that calls testrunner.bat and constructs the command line based on the parameters/parameter values I add.  The command line constructed is attached, along with the subsequent error:

[Step 1/1] The syntax of the command is incorrect.
[Step 1/1] Process exited with code 255

I have compared it to another SOAP project that runs successfully in TeamCity, and save for a few additional parameters in the other project, they look similar. In addition, I can run my test suite in SOAPUI successfully.  

Is there a way to troubleshoot where in my command line it is failing? Are there any restrictions that I'm not aware of using OpenSource to do this?
