Hello,
Indeed, if your 'Omit_Optional_Partx' targets are not part of any
depends attribute, they will not get called.
You should probably have something like:
<target name="buildall" depends="verify_switches, Omit_Optional_Part1,
Omit_Optional_Part2, Omit_Optional_Part3">
...
</target>
<target name="verify_switches" description="Let the user choose which
content to omit.">
...
</target>
<target name="Omit_Optional_Part1" description="Omit optional part 1"
if="omit.optional.part1">
...
</target>
<target name="Omit_Optional_Part2" description="Omit optional part 2"
if="omit.optional.part2">
...
</target>
<target name="Omit_Optional_Part3" description="Omit optional part 3"
if="omit.optional.part3">
...
</target>
Rgds,
Patrick
