[MPH-217] help:effective-pom does not show the value for a POM's "packaging"

**[Gary D. Gregory](https://issues.apache.org/jira/secure/ViewProfile.jspa?name=garydgregory)** opened **[MPH-217](https://issues.apache.org/jira/browse/MPH-217?redirect=false)** and commented

Running "mvn help:effective-pom" does not show the value for a POM's "packaging" value.

It's not clear from the site documentation if "packaging" is inherited from the parent POM or not.

I understand the default is "jar".

I expect to see the "packaging" value when running "mvn help:effective-pom" so I can understand if the value is being picked up from a parent POM or if it is defaulting to "jar".

TY.

**Affects:** 3.5.1

Start by reproducing the issue with `mvn help:effective-pom` on a project whose packaging is inherited or omitted, and inspect how the effective POM is rendered. Trace the help plugin entry point responsible for this goal. Done means the output shows the POM's packaging value and distinguishes inherited packaging from the default `jar`.
