How do I compile in debug mode? (netbeans, java, maven)

Question

I am facing annotation/persistence errors in a project and the persistence library throws a

NullPointerException when trying to resolve the entitie

Answer 1

From what I understand, you want debug in the compilation- not maven in debug mode.

Using mvn to compile, use debug mode through following way:

    org.apache.maven.plugins
    maven-compiler-plugin
    3.8.1
    
        8
        8
        true
        lines,vars,source 
    
 

debuglevel can be any of the three values entered in CSV format To highlight, debug and debuglevel are important nodes included in the maven.

Hope it helps in some way.
