\subsubsection{Rules}
If an id exists in both the parent and child pom and the ids are equal, then join the nodes, otherwise inherit the node.
\subsubsection{Plugin Execution ID Rules}
If a Plugin Model Container is joined by ID, the following rules apply:
\begin{enumerate}
\item Can not have two or more execution elements lacking an ID.
\item If default-execution-id is explicitly defined as the execution id, it is treated as not having an id for purposes of the above rule.
\item Project.Build.Plugins.Plugin.Executions.Execution.Goals is always joined on an execution id match. Duplicate goals are removed.
\end{enumerate}
The above rules also apply to joining with a pluginManagement node.
\subsection{Plugin Configuration Inheritance}
Plugin nodes are treated as a set. If a child pom contains the same element as a parent pom, then the parent pom element will not be inherited/joined unless the child element contains a property combine.children="append". In this case, it will treat the element as a collection.
