Subject Re: getting the exec task to run a script which spawns a child process
Date Tue, 01 Apr 2003 00:18:06 GMT
I tried this; now the exec task doesn't hang but the bar process still stops when the ant process
stops.  Is there a way to get bar to run indefinitely?

inside of it, which spawns a background child process. finishes pretty quickly, but
the exec task waits for bar to finish before moving on.  This is a problem for me because
bar is supposed to run indefinitely.

which explains a workaround for getting to run indefinitely.  Do I use the same workaround
