What is done during the creation of an archetype?

* Property resolution

    First, the Archetype Plugin asks the user to provide the common properties'
    values (<<<archetype.groupId>>>, <<<archetype.artifactId>>>, <<<archetype.version>>>,
    <<<groupId>>>, <<<artifactId>>>, <<<version>>>, <<<package>>>).

    Then it asks for additional properties.

* Archetype creation

    Using the project's directory as sources, <<<filteredExtensions>>> and <<<languages>>>
    properties, the module tree; the Archetype Plugin searches for relevant
    filesets indexed by module.

    Using the relevant filesets, the module tree, the resolved properties; the
    Archetype Plugin creates the archetype's resources.

    Then it creates the archetype's descriptor.

    Finishing by creating the POM for the archetype as a project.

* Archetype testing

    If you are creating an archetype from existing project all the tests from src/<it/projects> folder
    will be executed at this point.

* Archetype installation

    Optionally, after creating the archetype, the Archetype Plugin installs the
    archetype in the local repository. And it updates the local catalog.

* Archetype deployment

    Optionally, after installing the archetype, the Archetype Plugin deploys the
    archetype to the remote repository.

* Interactive mode

    The default behaviour is to operate in batch mode. The interactive mode is
    optionally used.

* Advanced batch mode

    In batch mode, the additional properties can only be defined using a property
    file. This file can also contain the other properties, both the common and
    <<<filteredExtensions>>> and <<<languages>>>.

* Fileset resolution

    In each module's directory and excluding submodules trees, the Archetype
    Plugin sorts the files by languages, filteredExtensions and sensible
    default base paths (src/main/<languages>, src/main/<siblings>,
    src/test/<languages>, src/test/<siblings>, ...).

    This defines a three-dimensional matrix. Each sorted group (matrix' cases)
    becomes a resolved fileset.
