Install -s mvn:org.camunda.bpm.extension.osgi/camunda-bpm-karaf-commands/4.0.0-SNAPSHOT

Hi,
I have installed karaf+camunda, but when I try to install camunda commands from karaf shell:
install -s mvn:org.camunda.bpm.extension.osgi/camunda-bpm-karaf-commands/4.0.0-SNAPSHOT
the state of bundle is failure, because missing (objectClass=org.camunda.bpm.engine.ProcessEngine) dependencies.
This is the stacktrace of exception:
org.apache.aries.blueprint.core - 1.7.1 | Unable to start blueprint container for bundle org.camunda.bpm.extension.osgi.karaf-commands/4.0.0.SNAPSHOT due to unresolved dependencies [(objectClass=org.camunda.bpm.engine.ProcessEngine)]
java.util.concurrent.TimeoutException

Help me, please.
Best regards
Antonio
