Poll only one SVN repo

I have a Jenkins project that pulls from two SVN repos (into two seperate directories). I want to poll just one of them , but can't find such an option. Is this possible?

File parameter without passing to MSBuild

I need to upload a file as a file parameter, put don't want it passed to MSBuild. I need the file in place to run the tests, but it is breaking my build with the following error: MSBUILD : error MSB1006: Property is not valid. I don't need it passed to the MSBuild. How do I set this?
