in terms of user-provided configuration from properties or the POM).
  If these mojos are to be first-class components, the configuration from these
  various sources must be consolidated and injected using the container.

  Currently, mojo configuration is done externally to the container, in the
  DefaultPluginManager in the maven-core API. In order to get from here to

 1. information is duplicate. once in POM's dependencies and once in the
 maven.multiproject.includes property.
 2. it works without problems only for projects with relative paths, e.g., from
 one CVS repository.. for projects from multiple SCM repositories it's harder
 to maintain the same relative links on all developer computers.
 not sure the unified source directory structure addresses this issue.

Maven 4 API - Immutable Settings Model

 This is strictly the immutable model for Maven settings in <<<org.apache.maven.api.settings>>> package.

 The following are generated from this model:

   * {{{./apidocs/index.html}Java sources}} with <<<Builder>>> inner classes for immutable instances creation.

 NOTE: If you change this file, you MUST bump the version up from 1.0. That is the version of the POM, and was
 used for releases of plexus-compiler and plexus-archiver in the past.

  What is it?
  -----------

  Maven is a software project management and comprehension tool. Based on
  the concept of a Project Object Model (POM), Maven can manage a project's
  build, reporting and documentation from a central piece of information.

  Documentation
  -------------

  The most up-to-date documentation can be found at https://maven.apache.org/.

  Release Notes
  -------------

A plugin manager would need to know how to find the dependencies of a plugin whether that be from a workspace of an IDE, a local Maven repository, or a remote Maven repository. During development in an IDE we would need layered resolution approach that would allow resolution from the workspace, then the local Maven repository and then from any number of remote Maven repositories. During development from the command line we would need a layered resolution approach that would allow resolution from...

<configuration/> element and <parameters/> element. From these elements we need to make a component configuration for the MojoExecution. The actual DOM like structure we create is of type PlexusConfiguration and is the type we use with the ComponentConfigurator to initialize fields in a Plexus component. Typically this is done within Plexus with the configuration supplied with component configuration, but in Maven we take configuration values from the POM. So we have to use the ComponentConfigurator...

     1. plugin goal execution in a child is usually simply appended (at end): you can't try to insert in the middle of pre-existing inherited executions,

     2. append happens at plugin level first, then goal level, independently from phases.
