Can't find task
I'm sorry if this is an RTFM or similar situation, but
I've looked through the source and binary distributions,
and can't find the answer to this problem:
In the HTML documentation on the Ant web site, there is
a doc page for a built-in task called <apply>. I've
seen this referenced by searching the ML archives as well.
But I can't find it anywhere in the 1.3 distribution!
Am I crazy? I want to use this task! Why does it seem
not to exist for me?
Thanks,
Dave

The regexp classes in ant rely on external regex libraries (namely Apache
oro, gnu.regexp and I believe Apache regexp). You need one of these for the
regexp mappers to work ;)

Thanks for the response, Glenn. Um, sure... well, what do you
mean "regexp jars"? It isn't necessary to have just the regexp
stuff in *separate* jars, is it? As I mentioned in my last message,
I tried putting the regexp classes into my classpath, and also
tried putting ant.jar, which contains these classes, into my
classpath, and ant was seemingly unable to find the classes in
either location.
So again, the question remains: what's missing here?
Incidentally, in my last message there was a mistake. I meant
to say that I had tried adding the flags
-Dant.regexp.matcherimpl=org.apache.tools.ant.util.regexp.JakartaRegexpMatcher
-Dant.regexp.matcherimpl=org.apache.tools.ant.util.regexp.JakartaOroMatcher
to my ant run as well, and that these hadn't worked, either.
Thanks,
Dave

Well, do you have the regexp jars in your classpath? The ORO dist can be found
at
http://jakarta.apache.org/builds/jakarta-oro/release/v2.0.1/
and the Regexp package at
http://jakarta.apache.org/builds/jakarta-regexp/release/v1.2/

Thats a fair point. Care to contribute a patch to the docs to fix it?

You should raise a documentation bug.

OK, so after the second person wrote exactly the same
thing, I started thinking :-) and cruising around the
documentation again... and stumbled upon a different
place in the documentation that said what and where
the jars were that are needed for this purpose.
So I downloaded the right one, put it in my classpath,
and bingo, it works.
Folks, I'd call this a "failure of documentation".
Looking only at the documentation for <mapper> was
not enough to tell me what I needed to know. In fact
it even says that "Ant comes with implementations for
jakarta-regexp and jakarta-ORO," which leads me to
believe that everything I need is already included
in the ant tarball, so of course I don't think I need
to go looking for something other than what I've
already got.
Oh well... that's life I guess :-)
Thanks again to those who responded.

Are the regexp jars in your classpath?

Thanks for the help. I'm beyond that problem now :-) The reason
ant was telling me it couldn't find the task, apparently, was because
I only tried to _run_ under Ant 1.2, but downloaded version 1.3 and
tar tv'ed, jar tv'ed, and grepped my way through it looking for
Apply.class and couldn't find it. Anyway, now that I'm actually
running 1.3, I've got <apply>.

Well, gee, that's intuitive :-)
----
Now I have a different problem. I can't get <mapper> to work right.
Inside my <apply> task, I've got:
<mapper type="regexp" from="(.*)\.p[lmhp]$$" to="\1.html" />
but when I try to run ant, now it tells me:
No supported regular expression matcher found
I've got both classes
org/apache/tools/ant/util/regexp/JakartaOroMatcher.class
org/apache/tools/ant/util/regexp/JakartaRegexpMatcher.class
in my $CLASSPATH (I'm running Solaris 8). I've even tried it
both with these classes out in the open filesystem and jarred up
inside ant.jar, and ant doesn't seem able to find them. I also
tried
ant
-Dant.regexp.matcherimpl=org.apache.tools.ant.util.regexp.RegexpMatcher
with no luck. Look, I've read the docs. And I realize you all can't
see
precisely what I'm doing, but I don't think I've missed anything major
here.
Why is this not working?
Thanks in advance,
Dave

In what way does it not exist for you? Do you get an error if you try to use
it, or have you tried to find it inside the jar? It physical name is
org.apache.tools.ant.taskdefs.Transform if that may be your problem? It
should be in the Ant 1.3 distribution, at least it's in the distribution I
downloaded (tar.gz).
