I did take a look at the configuration file.
but i thought that is was very confusing. I'm a windows user and opened it up in a webeditor. I couldnt pinpoint the exact location to put the command in the file.
can you tell me wich line number to put the command

It doesn't matter where the property is added, although if you add it more than once the last entry will be used.

However I've updated my previous post so you don't need to add anything to the configuration file, just pass the property on the command line. Also, I don't recommend creating a configuration file at all unless you need to override default properties - the sample file on github is just an example, it's not what you're meant to install (I think I will change that by commenting out all the lines...).
