> Looking at MNG-7772, this should not require any code change, but it's all about configuration.
> I propose to load / interpolate the following files:
>  * {{${maven.home}/conf/maven.user.properties}}
>  * {{${maven.home}/conf/maven.system.properties}}
> Those files would be used to load additional user properties and system properties for Maven.  In addition to the simple interpolation mechanism, we should provide two enhancements using special keys {{{}$\{includes{}}}} and {{{}$\{optionals{}}}} which would be used to load additional referenced configuration files such as:
> {{    ${optionals} = ${user.home}/.m2/maven.user.properties, ${session.rootDirectory}/.mvn/maven.user.properties}}
> Being loaded early when Maven is loaded, those files could reference directories to load extensions from:
>   {{{}maven.core.extensions.directories = ${session.rootDirectory}/.mvn/extensions.xml,{}}}{{{}${user.home}/.m2/extensions.xml,${maven.home}/extensions.xml{}}}
>  
> In various places, the maven code could be simplified and offer more configuration points at the same time.
