Mac version: opts -G, -D not recognized from commandline

[SoapUIProGroovyScriptEngineFactory] Setting Script Library to [/Applications/eviware/soapUI-Pro-3.6.1.app/Contents/Resources/app/bin/scripts]
org.apache.commons.cli.UnrecognizedOptionException: Unrecognized option: -G

So I cannot set properties from the commandline?? (This is the mac version, 3.6.1)
