I'm working with the latest CruiseControl.Net 1.5.7256.1.
I'm trying to use one of the system parameters, CCNetWorkingDirectory under sourcecontrol block and the project failed to recognize this parameter.
<sourcecontrol type="svn">
    <trunkUrl>https://padev/svn/physical/Source</trunkUrl>
    <workingDirectory>$[CCNetWorkingDirectory]\SVN\Source</workingDirectory>
    <username>ccnet</username>
    <password>hidden</password>
</sourcecontrol>
I also tried it as $CCNetWorkingDirectory, $(CCNetWorkingDirectory), Non of these option worked.
Thank you
