how can stop build proccess in a sub task?

[edumudi.viswan...@oracle.com]

I have target like <target name="main_task" depends="sub_task1, sub_task2" />, 
which depends on sub_task1, sub_task2. 

So subtasks  are <target name="sub_task1">  & <target name="sub_task2>  .

 

if I feel some task didn't do its work proper way in any one of subtasks, how 
can I stop build process in middle of subtask(s)?

 

thanks & regards,
