Re: How to hide output of an -- what about
While waiting for a <redirector> fix (which will
neccesiate a move to 1.6.3) I wonder if I can use
<presetdef> to solve my problem (though maybe not as
elegently).
Define a presetdef for each <exec> for the standard
(console output) invocation. Inside the main script
use a simple <if> check on the presence of an
${output.file} property and use that (instead of
calling the <exec> task directly), i.e.:
<if>
<isset property="output.file"/>
<then>
<imp.exe.predef output=${outputfile}/>
</then>
<else>
<imp.exe.predef/>
</else>
</if>
Am I using the <presetdef> correctly?

Not that I can tell. In pure Ant:
<target name="foo" depends="file,nofile">
<myexec executable="whatever" />
</target>
<target name="file" if="output.file">
<presetdef name="exec">
<exec output="${output.file}"
</presetdef>
</target>
<target name="nofile" unless="output.file">
<presetdef name="exec">
<exec />
</presetdef>
</target>
