From the command line I want the user
to specify which version of a
product they would like to build.
This way I can execute a specific
target within my build.xml
which corresponds to that
particular product. Here is an example:



From the command line:

c:ant in>perl runant.pl -D{p1}=



This will tell me that the user wants
to build product 1.


Now inside my build.xml I have the
following target:






This seems to allow for this target to
be executed if the command line
parameter was specified
as '-D{p1}='. I have seen no documentation
about this however, I came upon it while
trying things out (I'm still very new to Ant).



Is there a way to specify within the
build file whether or not to
execute a target using the 'if'
without using command line args?



Thanks,
