  <artifactId>tycho-surefire-plugin</artifactId>
  <configuration>
    <systemProperties>
    
      <!-- ... -->
    
      <osgi.console>1234</osgi.console>

      <bundle>
        <id>org.eclipse.equinox.console</id>
        <level>4</level>
        <autoStart>true</autoStart>
      </bundle>
      <bundle>
        <id>org.apache.felix.gogo.command</id>
        <level>4</level>
        <autoStart>true</autoStart>
      </bundle>
      <bundle>
        <id>org.apache.felix.gogo.runtime</id>
        <level>4</level>
        <autoStart>true</autoStart>
      </bundle>
      <bundle>
        <id>org.apache.felix.gogo.shell</id>
        <level>4</level>
        <autoStart>true</autoStart>
      </bundle>
    
      <!-- ... -->
      
    </bundleStartLevel>
  </configuration>
</plugin>

Then you can

telnet localhost 1234

to the OSGi console and use it as usual.
