Hi All,

If I have a target like this,

<target name=3D"C" depends=3D"A, B" if=3D"some_property_set">
	Some tasks...
</target>

If, 'some_property_set' is not set, target C is not executed, but the
targets in the 'depends' list get executed. How to avoid execution of
these targets?

I do not want to have the same <if=3D"some_property_set"> in the targets =
A
& B, as they may be called from other targets and the value of
'some_property_set' property, may not be relevant in the targets A & B
at that time.

Regards,
Vinod.

Hi,
I do not know what this is due to. Can you post you
ant script to see how you use <sql> task.
