dependency:unpack doesn't seem to handle version ranges

When I use the dependency unpack goal and a version range as shown below, Maven cannot download the artifact from the repository. There is a version 1.4.1 in the repository. If I use the specific version number 1.4.1. It works.

<build>
<plugin>

<groupId>org.codehaus.mojo</groupId>

<artifactId>dependency-maven-plugin</artifactId>

<executions>

<execution>

<id>unpack</id>

<phase>compile</phase>

<goals>

<goal>unpack</goal>

</goals>

<configuration>

<artifactItems>

<artifactItem>

<groupId>my.package</groupId>

<classifier>res</classifier>

<outputDirectory>$
