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

You can use Maven Help Plugin and help:system goal, so your pom will be:

    4.0.0
    testMavenOpt
    testMavenOpt
    jar
    1.0-SNAPSHOT
    testMavenOpt
    http://maven.apache.org
    
        
            junit
            junit
            3.8.1
            test
        
    
    
        
            
                org.apache.maven.plugins
                maven-help-plugin
                2.1
            
        
    

and you should execute mvn help:system
