[ccnet-user] Stop on error - how to implement

[GHarmonDDVA]

I have the following tasks in a task block.  If one of them fails, I
want the execution flow to stop instead of going to the next <exec>.
But, I can't find a way to stop if one of the previous <exec>'s has
failed.  Any information would be greatly appreciated.


                <tasks>
                        <exec>
                                <executable>c:\BuildTest\RTS.exe</executable>
                                <buildArgs>/s:55/qcbin /n:DCS_REL /d:QTP_REL 
/u:ghn /p:***** /
f:Root\QAREL /t:Open_Close /l</buildArgs>
                                <buildTimeoutSeconds>1200</buildTimeoutSeconds>
                        </exec>

                        <exec>
                                <executable>c:\BuildTest\RTS.exe</executable>
                                <buildArgs>/s:55/qcbin /n:DCS_REL /d:QTP_REL

                                <buildTimeoutSeconds>120</buildTimeoutSeconds>
                        </exec>

                        <exec>
