Option to discard (error) output?
Hi
https://bz.apache.org/bugzilla/show_bug.cgi?id=62330 reminded me of
something I wanted to discuss.
Sometimes people are simply not interested in the (error) output of a
process started by Ant at all. This is not supported directly as we send
output to the log unless you redirect it to a file or property.
People work around this limitation by sending output to /dev/null on
Unix or "nul" on Windows (which we broke) making the build file
dependent on the OS. Or they write to a property that is never used, but
this consumes memory.
I suggest to add discardOutput/discardErrorOutput properties to
redirector - and exec/apply/java for convenience - which would use
NullOutputStreams to allow pumping of streams without storing the
results anywhere.
Does this sound reasonable?
Stefan

Hello Stefan,
Yes that sounds reasonable to me and even the set of tasks that you
noted to have these properties.
