Description

The build for plexus-classworlds is currently failing because the POM snippet:

<plugin>
  <groupId>org.apache.maven.plugins</groupId>
  <artifactId>maven-dependency-plugin</artifactId>
  <version>2.0</version>
  <executions>
    <execution>
      <phase>generate-test-resources</phase>
      <goals>
        <goal>copy</goal>
      </goals>
      <configuration>
          <artifactItems>
            <artifactItem>
              <groupId>ant</groupId>
              <artifactId>ant</artifactId>
              <version>1.6.5</version>
            </artifactItem>
            <artifactItem>
              <groupId>commons-logging</groupId>
              <artifactId>commons-logging</artifactId>
              <version>1.0.3</version>
            </artifactItem>
            <artifactItem>
              <groupId>xml-apis</groupId>
              <artifactId>xml-apis</artifactId>
              <version>1.3.02</version>
            </artifactItem>
          </artifactItems>
          <outputDirectory>${project.build.directory}/test-lib</outputDirectory>
      </configuration>
    </execution>
  </executions>
</plugin>

ends up as the effective POM

<plugin>
  <groupId>org.apache.maven.plugins</groupId>
  <artifactId>maven-dependency-plugin</artifactId>
  <version>2.0</version>
  <executions>
    <execution>
      <phase>generate-test-resources</phase>
      <goals>
        <goal>copy</goal>
      </goals>
      <configuration>
          <artifactItems>
            <artifactItem>
              <groupId>ant</groupId>
              <artifactId>ant</artifactId>
              <version>1.6.5</version>
            </artifactItem>
          </artifactItems>
          <outputDirectory>${project.build.directory}/test-lib</outputDirectory>
      </configuration>
    </execution>
  </executions>
</plugin>

i.e. all but the first <artifactItem> element are lost.
