Is there a way to trace origin of a property in maven pom?

Question

I have a complex maven project with a lot of managed dependencies, and have a little problem tracing versions of these dependencies. For example, spring libraries\' version is g

You could give help:effective-pom a go. Just make sure that you use the 3.2.0 version (or later) together with the -Dverbose=true flag set. This will print out the source of the POM value.

To force the right version of the plugin:

    
      
        
          maven-help-plugin
          3.2.0
        
      
    

To use it:

%> mvn help:effective-pom -Dverbose=true 

This will print out the following:

    spring-boot-starter-parent
