Subject Option to discard (error) output?
Date Sun, 14 Mar 2021 11:25:19 GMT
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
