Maven Ant Tasks: provided dependencies don't exclude trans

[Kevin Stembridge <ke...@gmail.com>]

Hi all,
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.

    <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>


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. 

If anyone can shed some light on why this isn't working for me that
would be great.

Cheers,
Kevin

Hi Kevin,

Strange question: the purpose of Maven Ant Tasks is specifically to get 
transitive dependency! :)

But if that's really what you want, I see 2 ways of doing it:

1. use exclusions to exclude transitive dependencies you don't want
<dependency groupId="org.springframework" artifactId="spring" version="2.0.7" 
scope="provided">
  <exclusion groupId="" artifactId=""/>
</dependency>

2. don't use Maven Ant Tasks but simply Ant's get task
<get 
src="http://repo1.maven.org/maven2/org/springframework/spring/2.0.7/spring-2.0.7.jar" 
dest="bogus"/>

regards,

Hervé
