cb:define name="myverion" did not work

[Jixiu Li]

Can anybody let me know what is wrong for the following config code?

     <cb:define name="myverion">   

  <exec>

        <executable>c:\Windows\System32\cmd.exe</executable>

        <buildArgs>

          /C  type "version.txt"

        </buildArgs>

      </exec>

     </cb:define>

myversion was defined to c:\Windows\System32\cmd.exe. I want to define as contained in version.txt

Thanks

Jixiu
