How to suppress Mavens INFO spam without suppressing normal output?

Question

I would like to use Mavens dependency:build-classpath to create a class path:

$ mvn dependency:build-classpath -Dmdep.prefix='lib' -f xpath.pom
[INFO] Scanning for projects...
[INFO]
[INFO] ------------------------------------------------------------------------
[INFO] Building xpath 1
[INFO] ------------------------------------------------------------------------
[INFO]
[INFO] --- maven-dependency-plugin:2.1:build-classpath (default-cli) @ xpath ---
[INFO] Dependencies classpath:

How can I stop Mavens INFO spam without suppressing the intended output of build-classpath?

I found answers, which explain that I have to use the -q option to suppress INFO output. But using this option results in no output at all.

I know I can use grep, but I would like to avoid it. And I can not believe that Maven can not do this out of the box, because it makes the dependency plugin quite useless.

This is the complete pom:

            </goals>
            <configuration>
              <outputDirectory>${project.basedir}/lib</outputDirectory>
            </configuration>
          </execution>
        </executions>
      </plugin>
    </plugins>
  </build>
</project>

I know this is not ideal for some, but you can use outputFile to have it put the output into a file.
