eliminate maven dependency duplication - maven-2

Question

In my Maven build, I use the antrun plugin to invoke an ant task.
<plugin>
<artifactId>maven-antrun-plugin</artifactId>
<executions>
<execution>
<phase>compile</phase>
<configuration>
<tasks>
<property name="plugin_classpath" refid="maven.plugin.classpath" />
<java classname="org.apache.tools.ant.launch.Launcher"
fork="true" failonerror="true">
<classpath>
<pathelement path="${plugin_classpath}" />
</classpath>
</java>
</tasks>
</configuration>
<goals>
<goal>run</goal>
</goals>
</execution>
</executions>
<dependencies>
<!-- DEPENDENCIES FROM PROJECT DUPLICATED HERE -->
</dependencies>
</plugin>
I need to duplicate all the project dependencies in the section indicated, so that they are available to the ant task. Is there a way to avoid this duplication, by referring to the project's dependencies instead of copy-pasting them?

Here's how you can do it:
<property name="plugin_classpath" refid="maven.plugin.classpath" />
<property name="compile_classpath" refid="maven.compile.classpath" />
<java classname="org.apache.tools.ant.launch.Launcher"
fork="true" failonerror="true">
<classpath>
<pathelement path="${plugin_classpath}" />
<pathelement path="${compile_classpath}" />
</classpath>
</java>
