java - effect of mvn -X option ? ie. corresponding property that can be detected inside poms? -

please enlighten me if there property maven sets when given -x option detected , passed script run exec plugin goal - ie. put java system property or environment variable says "user has given -x option on command line", like:

  
 <environmentvariables>    <enable_debug>${maven.some.property.set.when.debug.is_enabled}    </enable_debug>  </environmentvariables> 
  

i've searched web, documentation , source code no avail.

aha ! found : (in maven-embedder/src/main/java/org/apache/maven/cli/logging/impl/log4j2configuration.java) :

public class log4j2configuration     extends baseslf4jconfiguration {     @override     public void setrootloggerlevel( level level )     {     ...        system.setproperty( "maven.logging.root.level", value );     } }
