You have a child pom that inherits from a parent pom, which may inherit from another and then some. You are not sure exactly what all is going on in the child pom.
The solution:
When you use inheritance in a pom it makes life easier. You don't need to know about all the stuff that was defined in the higher level POM, it just works. Then there are times when you get into some fancy Maven configuration and you really need to troubleshoot a problem that could be inheritance related. This one is dirt simple:
mvn help:effective-pom
By typing this on the command line you can get the full configuration that is being used in your project. This is done by merging all the parent configuration with your projects configuration, and then displaying it in the terminal.
