How to print the actual MAVEN_OPTIONS that are being used?

Question

Is there a way to get maven to output the value of environment and maven variables during a build? This would be very useful for debugging things when they\'re going wrong.

Answer 1

It'll require some changes to the pom.

  org.apache.maven.plugins
  maven-antrun-plugin
  1.1
  
    
      validate
      
        run
      
      
        
          [MAVEN_OPTIONS]${env.MAVEN_OPTIONS}
        
      
    
  

Of course, it might be simplest to run

echo $MAVEN_OPTS
