Running SoapUI TestRunner from Jenkins problem

I am using SoapUI 4.0.1 and interfacing with Jenkins.

When I use the "run windows batch" option for the build, I use this string:
"C:\Progra~1\eviware\soapUI-Pro-4.0.1-SNAPSHOT\bin\testrunner.bat" -r -j -f"C:\Progra~1\Jenkins\workspace\SoapUI\Reports" -g -I -PRegularWebserviceEndpoint=http://secretURL.com -PServiceEndpoint=https://secretURL.com "C:\Documents and Settings\cheetara\test\Thundercats-soapui-project.xml"

Works great (I know it says snapshot, but it's really the non-beta-mode).

I wrote an ANT script

<exec executable="cmd.exe" failonerror="true">
     <arg value="/C &quot;&quot;C:\Progra~1\eviware\soapUI-Pro-4.0.1-SNAPSHOT\bin\testrunner.bat&quot; -r -j -f&quot;C:\Progra~1\Jenkins\workspace\SoapUI\Reports&quot; -g -I -PRegularWebserviceEndpoint=http://secretURL.com -PServiceEndpoint=http://secretURL.com &quot;C:\Progra~1\Jenkins\workspace\SoapUI_SVN\Thundercats-soapui-project.xml&quot;&quot;"/>
    </exec>

When I tell jenkins to do an ANT Build, I get this:

Anyone know what I missed or what is needed as a parameter when running ant? This is not a maven build cause I have no idea how to do it (the information provided is not updated).
