Hi friends,
I am working with cruisecontrol using vss.I am getting problem like this
and if i create the same file which it is expecting then i'm able to access this but again its deleteting the tmp file automatically and its giving same error how can i create this tmp file before it is going to build.
here is my code

<vss vsspath="//build//cruisecontrol-bin-2.5//projects//${project.name}" <br /> login="geeta,Geeta@123" <br /> serverpath="C:\Program Files\Microsoft Visual Studio\VSS"/>

and here is output in console
