Description

Hi,
I recently started to develop my own Maven-Plugin and came across the Mapping of "Mapping Complex Objects" (see: https://maven.apache.org/guides/mini/guide-configuring-plugins.html#Mapping_Complex_Objects).
I thought it would be nice to develop my own Plugin with a "Complex Object" which also contains a required or a default parameter inside (e.g. Person is my Complex Object and the firstName is a required Parameter and lastName's default is Doe).
Unfortunately this doesn't work at all and both Parameters end up being "null"

I thought the problem is based on the "maven-plugin-annotations" I use for the Plugin, but chaging the Version does not change the Outcome (both Parameters are still null).

For convenience reason I attached a Sample-Project where the Problem occurs as well.

I tested a couple of different Versions of the "maven-plugin-annotations" and a lot of different Apache Maven Versions, something like:
<!-- Broken with: 3.1, 3.2, 3.3 with Apache Maven 2.2.1 -->
<!-- Broken with: 3.1, 3.2, 3.3 with Apache Maven 3.0.5 -->
<!-- Broken with: 3.1, 3.2, 3.3 with Apache Maven 3.1.1 -->
<!-- Broken with: 3.1, 3.2, 3.3 with Apache Maven 3.2.3 -->
<!-- Broken with: 3.1, 3.2, 3.3 with Apache Maven 3.1.1 -->
<!-- Broken with: 3.1, 3.2, 3.3 with Apache Maven 3.2.3 -->

I also tested with the following two Java-Versions
JAVA 1.6:
java version "1.6.0_45"
Java(TM) SE Runtime Environment (build 1.6.0_45-b06)
Java HotSpot(TM) 64-Bit Server VM (build 20.45-b01, mixed mode)

JAVA 1.7:
java version "1.7.0_51"
Java(TM) SE Runtime Environment (build 1.7.0_51-b13)
Java HotSpot(TM) 64-Bit Server VM (build 24.51-b03, mixed mode)

Any Suggestions?

PS: If this is the "wrong" place to report this Problem please let me know where I can report it
PSS: You can use "mvn clean install && mvn clean package -Pdemo" to check the result of the Nested-Object Parameters. The Build will fail everytime, but that's not the point...
