Unsolved qmake install detect fail

I'm using qmake/nmake/nmake install to deploy a library that is a dependency using jenkins. The problem is that if copy fails (say the file is in use) the build will still be marked as successfull in jenkins. Do you have any idea how to force the failure if a file is not actually copied?

Jenkis output:

The process cannot access the file because it is being used by another process.
        0 file(s) copied.

C:\MyProject>exit 0 
Finished: SUCCESS

Hi,

How are you doing that part in Jenkins ? Running a script ?

[VRonin]

Yes, just a straight simualtion of the cmd console

Just as idea: If you can't get the copy command give you successful failing information, how about checking the result aftewards? E.g. with exists.
