NullPointer Exception when starting build.

Hi all,

I've configured a build definition in RTC with the option 'Delete directory before loading' checked and my build ran successfully.

When I uncheck the 'Delete directory before loading' option the build fails with the following error.

Please can somebody explain to me why I receive this exception and how to solve this, without checking the option 'Delete directory before loading'?
