Uh, I'm a little
lost here. Sorry, beginner question.
I want to detect if
a property has/has not been defined and do conditional processing based on
whether or not the property exists. I thought I should
do:
<project
name="test">
<property if="${property::exists(XYZ)}" name="IsItThere" value="yes"/>
</project>
<property if="${property::exists(XYZ)}" name="IsItThere" value="yes"/>
</project>
And then I run
it:
C:\build\BuildIt>nant -f:prop.build

But that always
complains that the property isn't defined. Uh, that's what I wanted to
detect...And no, using overwrite="false" is not what I need...this is a
simplified example. Anybody have any
ideas?
