You would like to have a copy of the effective pom file used in your project. The effective pom is your current projects pom merged with any inherited poms.
The solution:
If you have read the post "Seeing the Big Picture with Inherited Poms" you know that by type "mvn help:effective-pom" a copy of the effective pom will be outputted to your screen. This is nice but what if you want a copy of this on file? Maybe you would like to attach it to an email, or use it to cut and paste together a new file. Well Maven has this one covered. Use the following command
mvn -Doutput=Where <filename><filename> help:effective-pom
