Description

I have an ANT script using maven antlib (alpha-3) as follows:

...

<target name="getdeps">
<artifact:remoteRepository
id="remote.repository" url="http://172.16.40.249/ourrepo" layout="legacy"/>

<artifact:dependencies verbose="true">
<remoteRepository refid="remote.repository"/>
<dependency groupId="sis2" artifactId="sis2-common" version="0.1"/>
</artifact:dependencies>
</target>

...

The central repository contains only artifacts with model-3.0.0 POMs (generated by Maven 1.1)

However when executing the ANT target I get the following exception:

— Nested Exception —
org.apache.maven.artifact.resolver.TransitiveArtifactResolutionException: Unable to read the metadata file
sis2:sis2-common:0.1:jar

from the specified remote repositories:
http://172.16.40.249/ourrepo
Path to dependency:
1) unspecified:unspecified:jar:0.0

The problem is that in the class DefaultModelValidator (apparently always called when retrieving a dependency) a check is done to verify whether the element <modelVersion> is present in the POM. However for model-3.0.0 POMs this element isn't defined in the XSD!
