I am reworking the WAR and SSDD targets in a build.xml file and am
trying to add some error checking. I can verify that individual

all the required frameworks in my ant.frameworks.wo.wolocalroot
file exist as jars in /Library/WebObjects/lib while building the
war file (like xcode does).
I can create the file list I need to check easily enough, but I am
not sure how to get ant to verify that a list of files exist, or
even iterate over a list checking them individually. I would
prefer to do this without having to add additional taskdef
dependencies other than woproject.
Any suggestions?
It is possible to do "if-then-else" style logic in ant. It is just
extremely awkward. To tell the truth, every time I need to do it, I
need to re-learn it. It is just very non-intuitive. You want to
look very carefully at the documentation for the <condition> task,
the <available> task and a few others. Maybe a third-party task
handles it more nicely.
Yes, functionality exists in the ant-contrib library I believe, but I
am trying to avoid additional dependancies if I can.
Ant is much happier trying to find a resource for you. If you want
to check whether the /System/Library/Frameworks/
JavaFoundation.framework directory exists and fail if it does not,
that is a bit awkward. If you want to say find the framework in one
place, or else in another, or finally in a third, ant is much
happier about doing that.
For example:
...
...
The words in the "unless" are the names of properties. One can, of
course, set a property to equal the property name. One ends up
expressing the "if-then-else" logic by setting properties and
keying actions off of them.
Not exactly crystal clear, no? But it is possible. It just ends up
looking weird.
That's not quite the problem I am trying to solve. I have a list of
files (not just one) that isn't known until runtime that gets
imported into a property with <loadfile> that I later use as a
<fileset> include list, but I want to verify they exist first. If one
doesn't exist then I want to print an error with its name and abort.
I need some way to iterate over a <filelist> if I am to use something
like <available> which only accepts a single file for evaluation.
