February 07, 2012 10:11 PM=0ATo: Ant Users List=0ASubject: Regarding exec t=
ask=0A=0AHi,=0A=0AI noticed that on windows, if I use the exec task to run =
a batch script which in turn starts other processes then if kill ant then t=
he sub-processes created by the batch script still continues to run. I did =
some research on google and found that the default java implementation of P=
rocess.destroy does not kill the child processes created by a process on wi=
ndows. I also found that there are some third party libraries like jvnet th=
at provide the capability of killing all processes created by a process on =
windows. So I thought of somehow extending the 'Execute' class of ant to us=
e the functionality of this 3rd party library, but I find that its difficul=
t if not impossible to extend this class. I can't find a way to provide my =
implementation of Process class that does something different when its dest=
roy method is called. Other core tasks such as java task directly create an=
 instance of the 'Execute' class which makes it difficult to globally chang=
e how a=0Aprocess is destroyed within ant. If anyone can provide some sugge=
stions on how this can be accomplished I will be very grateful.=0A=0A=A0Cur=
rently the build scripts of my project uses the exec task to run a bunch of=
 batch scripts in parallel which in turn execute sql scripts by starting of=
f another process. I have written the ant script such that if any sql scrip=
ts fail then the ant build fails.When the build fails I notice that all the=
 batch scripts have terminated as expected but the processes spawned by the=
se batch scripts still continue to run.=0A=0AAny help is greatly appreciate=
