Oh I completely understand :) No worries :)
I tend to go overboard with Ant. To be honest, I use it as more than a
build environment...I use it as a cross platform scripting language :)
Anyway, you can probably do the same thing with beanshell or another
scripting language directly from within your Ant script. The simplest
thing I found was to use regular expressions (which is what my example
does). I used a macrodef as a kind of reusable function I can call...
I am unaware of a substring task at all. Ant Contrib (a third party Ant
library) has some fairly useful features...I really use the heck out of
it...
Again, if you want substring or the like you can, perhaps, write your own
Ant task in Java...or as I mentioned do so using a scripting language...
I find Beanshell really useful and do some stuff with it on occasion...

Hi, thanks for your answer.
Uhhh, I am an absolute ant newbie.
I do not believe it. All this is needed just to remove a prefix prom a
string?!
Let me know if you have any questions...
Ant proper really is not capable to perform things that look in C like
char * prefix;
char * path;
char * suffix = path + strlen (prefix);
or like
String prefix;
String path;
String suffix = path.substring (prefix.length());
in Java?
I am trying to *simplify* Makefiles by using ant. And not to make things even
more complex and harder to understand and to maintain.
If ant cannot do it, it is not what I am looking for...
All I could find is a strlen:
<length property="prefix.length" string="${prefix}" />
So what is missing is something like substring or an analogon to basename
that can remove a prefix instead of a suffix.
I am using Ant Contrib's propertyregex task to do this... Adjust URI's,
etc for your needs :)
The URI in your macrodef?
To that value must it be set? To kerberos zip?
Or to one of the jars in it?
Please be kind, I am just trying ant to look if it can make things simpler.
