maven copy-dependencies includeGroupIds and all transitive elements to those

Question

I try to figure out how to copy all dependencies to an explicit version and all the required dependencies.

For Example: My project requires version 3 of a third party lib, called foobar. I want to copy the version 3 libraries to a folder named lib-foobar-${foobar.version}.
In this folder are those jars which are required to use foobar in version 3. That means the jar itself and all dependent jars which are declared in the foobar pom.

I currently use the org.codehaus.mojo:maven-dependency-plugin:2.1 with goal copy-dependencies in phase package.
My configuration is:

<configuration>
    <outputDirectory>${project.build.directory}/lib-foobar-${foobar.version}</outputDirectory>
    <includeGroupIds>com.foobar</includeGroupIds>
    <excludeTransitive>false</excludeTransitive>
    <excludeScope>test</excludeScope>
    <includeScope>compile</includeScope>
</configuration>

I don't want to list all allowed and not allowed lib's because a step to a newer version takes place every month.

Are there any other tools which can do that or is there any dodge for that?

Big thanks to user944849.

It was very helpful to me for finding out the best solution in that case.

For everyone who is interested in my solution, here it comes:

At first I changed the plugin to maven-assemby-plugin and added a new assembly file

      <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-assembly-plugin</artifactId>
        <version>2.4</version>
        <dependencies>
           <dependency>
            <groupId>com.foobar</groupId>
            <artifactId>foobar-parent</artifactId>
            <version>${foobar.version}</version>
            <type>pom</type>
          </dependency>
        </dependencies>
        <executions>
          <execution>
            <id>copy-foobar</id>
            <phase>package</phase>
            <goals>
              <goal>single</goal>
            </goals>
             <configuration>
                <descriptors>
                  <descriptor>src/assemble/foobar-libs.xml</descriptor>
                </descriptors>
            </configuration>
           </execution> 
         </executions>
      </plugin>

And the assembly file looks like:

<assembly
  xmlns="http://maven.apache.org/plugins/maven-assembly-plugin/assembly/1.1.2"
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="http://maven.apache.org/plugins/maven-assembly-plugin/assembly/1.1.2 http://maven.apache.org/xsd/assembly-1.1.2.xsd">
  <id>standalone</id>
  <formats>
    <format>dir</format>
  </formats>
  <includeBaseDirectory>false</includeBaseDirectory>
  <dependencySets>
    <dependencySet>
      <includes>
        <include>org.foobar</include>
      </includes>
      <outputDirectory>/lib-foobar-${foobar.version}</outputDirectory>
      <useProjectArtifact>true</useProjectArtifact>
      <useTransitiveFiltering>true</useTransitiveFiltering>
      <unpack>false</unpack>
    </dependencySet>
  </dependencySets>

</assembly>

The key was the <useTransitiveFiltering> element, which resolves all transitive libs based on the included libs.
