Thanks, that was what I needed. Well, at least it got the <script> task
working. Now I have a similar problem with the <replaceregex> task, but
that's got to be an Ant issue since it should be picking up what it
needs from the JVM. I'll follow that up on the Ant Users list.
Thanks,
L.

Thanks for the link, I missed that page when I was documentation
hunting. However, I don't quite see how it helps in this case, since (a)
the <script> task doesn't accept a nested <classpath> and (b) I want to
set the classpath Ant gets called with, not modify the Ant build in a
way that would make it break outside of Maven.
What I really need is a way to configure the plugin such that it invokes
Ant with a specified system classpath (assuming the <script> and other
tasks I need to get working define build.sysclasspath behaviour
equivalent to 'only' or 'first', that is).

"Using optional ant tasks"
On 3/9/06, Laurie Harper <[EMAIL PROTECTED]> wrote:
I'm trying to integrate a third-party, ant-based build into a Maven2
build using the antrun plugin. The problem is the ant build uses
optional tasks, and I can't figure out how to get that to work.
The ant build as shipped copies the required dependencies (jar files)
for the optional tasks to ~/.ant/lib to make them available to ant and
this works fine when calling ant from the command line, but not when
invoking ant from Maven. In any case, I'd rather skip that requirement
by putting the jars on ant's classpath via some configuration in my POM.
I've tried everything I can think of, but the antrun plugin always gives
me the standard ant error message, 'Ant could not find the task or a
class this task relies upon.'. For example, a simple test:
build.xml:
<?xml version="1.0" encoding="iso-8859-1"?>
<project name="script-test" default="script-test" basedir=".">
<target name="script-test">
<script language="javascript"><![CDATA[
//alert("Javascript OK");
]]></script>
</target>
</project>
pom.xml:
<project xmlns="...>

Embedded error: The following error occurred while executing this line:
/Users/laurie/tmp/mvn-ant-script/build.xml:4: Could not create task or
type of type: script.
Ant could not find the task or a class this task relies upon.
This is common and has a number of causes; the usual
solutions are to read the manual pages then download and
install needed JAR files, or fix the build file:
- You have misspelt 'script'.
Fix: check your spelling.
- The task needs an external JAR file to execute
and this is not found at the right place in the classpath.
Fix: check the documentation for dependencies.
Fix: declare the task.
- The task is an Ant optional task and the JAR file and/or libraries
implementing the functionality were not found at the time you
yourself built your installation of Ant from the Ant sources.
Fix: Look in the ANT_HOME/lib for the 'ant-' JAR corresponding to the
task and make sure it contains more than merely a
META-INF/MANIFEST.MF.
If all it contains is the manifest, then rebuild Ant with the needed
libraries present in ${ant.home}/lib/optional/ , or alternatively,
download a pre-built release version from apache.org
- The build file was written for a later version of Ant
Fix: upgrade to at least the latest release version of Ant
- The task is not an Ant core or optional task
and needs to be declared using <taskdef>.
- You are attempting to use a task defined using
<presetdef> or <macrodef> but have spelt wrong or not
defined it at the point of use
Remember that for JAR files to be visible to Ant tasks implemented
in ANT_HOME/lib, the files must be in the same directory or on the
classpath
Please neither file bug reports on this problem, nor email the
Ant mailing lists, until all of these causes have been explored,
as this is not an Ant bug.

Note: I'm using <scope>system</scope> because some of the JAR files used
by the third-party bulid script are custom versions that ship with that
product.
Note: I want to hook the call to ant into the generate-resources
lifecycle phase if possible, though I could live with hooking it into
the compile phase if necessary to get the right classpath passed in to Ant.
Note: I've tried various combinations of inheritAll and inheritRefs on
the <ant/> task in pom.xml without any luck.
Is there something simple I've missed, or is it just not possible to use
Ant optional tasks with the antrun plugin?
Thanks,
L.
