Rainer,
You couldn't be more wrong about the lack of documentation of the non-use of
the ${} notation in if / unless.
The section about targets DOES NOT say that you don't use the ${} notation for
if / unless. It does say this, however:
'This is done by placing the property name between "${" and "}" in the
attribute value.'
which leads you to believe that you need ${} notation wherever you need a
property in an attribute, such as in if / unless.
How about helping your users out and making it clear that you don't use ${}
notation with if / unless, in marked contrast to everywhere else in Ant.
Since if / unless are apparently the only place in Ant where you don't use ${}
notation that fact should also be pointed out explicitly so people don't forget
the ${} notation elsewhere.

${} refers to the value of a property.
if / unless attributes refers to the existence (i.e. name) of a property.
IMHO, the different notation is reasonable.
However, this syntax and behaviour is pointed out explicitely in the manual:
->Using Ant->Targets

Betreff: Need documentation change for if / unless
I filed this bug regarding the use of the if and unless attributes of
:
http://issues.apache.org/bugzilla/show_bug.cgi?id=44315
Matt Benson pointed out that the problem is that you don't use the ${}
notation when naming a property in an if or unless attribute. This is
confusing because everywhere else in Ant when you reference a property you
use the ${} notation.
The documentation for Targets doesn't mention this:
http://ant.apache.org/manual/using.html#targets
The fact that you don't use ${} notation for the if / unless attributes
needs be made explicit in the documentation.
Are there any other places where you use a property without using the ${}
notation? If so these also need to be made explicit. If the if / unless
attributes are the only place where this applies that should also be noted
in the documentation for if / unless.
Thanks.
Dean
