Hi Herve,
I sent the following reply to you on the user's list but it got bounced as

Hi Herve,
Thanks for the reply.
I'm not so sure that the purpose of the Ant tasks is to specifically get
transitive dependencies. I would say that its purpose is to make use of Maven's
dependency management features, transitive dependencies being one of them, but
scope recognition being another. (The first paragraph on the Maven Ant Tasks
site would seem to back me up on this ). It seems to me that it is failing on
the scope recognition part of it.
The documentation on the site is pretty clear that declaring a dependency with
provided scope is supposed to behave the same way for the Ant task as it does
for Maven itself. So I think we've got a bug here. Even if its not a bug, it
would still be nice to implement this scope recognition as per the Maven
dependency mechanism. That would be much more preferable than having to add
exclusion elements or perform an Ant get. As a side note, I've decided to use
the Ant copy task to copy the artifacts directly from my local Maven repo.
I'm going to raise a JIRA for it and see what the dev team thinks.
Thanks for your help and suggestions.

Here is the paragraph I am referring to from the top of the [Maven Ant Tasks
site|http://maven.apache.org/ant-tasks.html]:

Maven comes with a set of Ant tasks that can be used to utilise Maven's
artifact handling features from within Ant. This includes:
* Dependency management - including transitive dependencies, scope
recognition and SNAPSHOT handling
* ...

And from under the section that describes the dependencies task:
{quote}
You can also specify a scope parameter on each dependency. This changes the
behaviour of transitive dependencies and is useful for building different types
of classpaths. To see how it affects the behaviour of the dependencies, see the
Dependency Mechanism documentation in the Maven 2.0 site.

I don't think you should be closing this issue. My opinion is that the
documentation is correct and the ant tasks should be consistent with the Maven
dependency mechanism. So either we have a bug or the documentation needs to
change.
Cheers,
Kevin

> Copied from a posting to the Maven users list:
> I'm trying to use the dependencies ant task to copy artifacts to a given
> location but I'm having trouble excluding transitive dependencies.
> My understanding from the documentation is that I should be able to use the
> following XML to copy an artifact, without its transitives. But, nothing at
> all gets copied.
> {code:xml}
> <target name="test">
>
> <artifact:dependencies filesetId="copy.test.fileset" useScope="provided"
> verbose="true">
> <dependency groupId="org.springframework" artifactId="spring"
> version="2.0.7" scope="provided"/>
> </artifact:dependencies>

> <copy todir="bogus" verbose="true">
> <fileset refid="copy.test.fileset" />
> <mapper type="flatten" />
> </copy>

> </target>
> {code}
> I've tried the following combinations of the useScope and scope attributes:
> ||useScope || scope || Result||
> |provided | provided | Nothing copied|
> |provided | runtime | Nothing copied|
> |provided | compile | Nothing copied|
> |runtime | provided | Nothing copied|
> |runtime | runtime | Dependency and transitives copied|
> |runtime | compile | Dependency and transitives copied|
> |compile | provided | Dependency and transitives copied|
> |compile | runtime | Nothing copied|
> |compile | compile | Dependency and transitives copied|
> Note that none of these configurations gives me a dependency without any
> transitives. I understand that I can specify exclusion elements to exclude
> all the transitives but it seems to me that specifying provided scope is
> supposed to achieve the same goal, and would be much nicer.
