Capturing Ant output in a way similar to Unix pipes

[Holger Rauch <ho...@heitec.de>]

Hi to all list members,

I've looked in the Ant manual and googled about the questions mentioned
below but unfortunately haven't found anything useful.

Is it possible to use the output of one Ant task as the input of another Ant
task (some sort of piping mechanism as it exists in Unix) without the usage
of intermediate temporary files? If so, how can this be done? 

Is it possible to access the standard file descriptors for
stdin (0), stdout (1), and stderr (2) directly from within Ant? If so, how?

Thanks in advance for any advice/pointers!

Kind regards,

	Holger

Some tasks support redirection of output via <redirector>, but I
believe that it's only <exec> and <java>, i.e. tasks using Execute
internally. This may be what you were looking for.

But I am not sure you can "pipe" things though, and that's certainly
not something you can do generically with any task in Ant. --DD
