How to supress output

[To...@aol.com]

Hello,

I am new to Ant.  My ant script sends out email at the end of each build via org.apache.tools.ant.listener.MailLogger.

The problem that I have is that our version control system, Perforce, produces so much output our emails become huge.  Is there a way to redirect the p4sync tasks output or "turn off" the MailLogger temporarily?

Thanks!

I recently raised a similar issue for ClearCase. In fact, I submitted an 
enhancement request.

http://issues.apache.org/bugzilla/show_bug.cgi?id=33169

One developer responded that no one had ClearCase, and so they couldn't test 
such a change even if they made it. Perhaps this issue could be addressed 
more generally for any task that does a Runtime.exec call internally.

In the meantime, I've worked around the problem in a clumsy way using the 
"exec" task to run another ant process as follows. It seems to work on 
Windows.

	<!--
		The file target used to discard output.
		"/dev/null" is standard for Unix-type systems.
		It's "NUL" on Windows.
	-->
	<property name="file.null" value="NUL"/>

	<!--
		The name of the shell used to invoke ant.
	-->
	<property name="shell.name" value="cmd.exe"/>

	<!--
		The name of the file used to invoke ant.
		"ant.bat works on Windows.
	-->
	<property name="ant.name" value="ant.bat"/>


	<!--
		Does the actual work of updating the ClearCase tree.
		Should be called by ccUpdate inside an exec task if
		standard-output suppression is desired.
	-->
	<target name="doCcUpdate">
		<ccupdate viewpath="${clearcase.viewpath}"/>
	</target>

	<!--
		Wraps the update in an exec to suppress verbose output
	-->
	<target name="ccUpdate">
		<echo level="info">Sending output to ${file.null}</echo>
		<exec executable="${shell.name}" output="${file.null}">
			<arg line="/c ${ant.name} doCcUpdate"/>
		</exec>
	</target>
