Answer 1

Your maven project structure seems broken. If you first clean install your parent project (which is xgroup:xserver:pom:1.0.1-SNAPSHOT ) and then clean install your child project and your problem will be fixed. But, it will be better if you fix your root problem. If you post your project structure, parent.pom etc. I can give you a more detailed answer.
