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

Add this plugin under plugins section in pom.xml and use mvn validate :

  org.apache.maven.plugins
  maven-antrun-plugin
  1.1
  
    
      validate
      
        run
      
      
        
          Displaying value of system variables
           ${env.YOUR_ENVIRONMENT_VARIABLE_NAME}
        
      
    
  

This will print your env variable value.
