Extracting Maven classpath from configuration

I need to find the classpath for maven somehow, i.e. all dependencies, etc., and use it as part of the config for the plugin. Here's an example

    ...<systemProperties>
        <systemProperty>
          <name>some.system.property.here</name>
          <value>${maven.runtime.classpath}</value>
        </systemProperty>
     </systemProperties>
    </configuration>...

Unfortunately, the $ {maven.runtime.classpath} property is empty. Is there anything that is equivalent to this?

The easiest way is to use something like groovy and configure it programmatically.

Here is the configuration to be enabled.



        <plugin>
            <groupId>org.codehaus.gmaven</groupId>
            <artifactId>gmaven-plugin</artifactId>

            <configuration>
                <source>
                    import org.codehaus.plexus.util.StringUtils;
                    import java.io.File;

                    System.setProperty("your.classpath.property", StringUtils.join(project.getRuntimeClasspathElements().iterator(), File.pathSeparator));
                </source>
            </configuration>

            <executions>
                <execution>
                    <phase>generate-sources</phase>

                    <goals>
                        <goal>execute</goal>
                    </goals>
                </execution>
            </executions>
        </plugin>

I'm not sure why the classpath is empty, maybe this will help: http://maven.apache.org/plugins/maven-antrun-plugin/examples/classpaths.html
