Maven 4 API - Immutable Maven Model

 This is strictly the immutable model for Maven POM (Project Object Model), so really just plain objects in <<<org.apache.maven.api.model>>> package.

 The following are generated from this model:

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

            List<ArtifactRepository> remoteRepositories,
            ArtifactRepository localRepository)
            throws RepositoryMetadataStoreException {
        // TODO currently this is first wins, but really we should take the latest by comparing either the
        // snapshot timestamp, or some other timestamp later encoded into the metadata.

 * resources
 *
 * We need to look at Maven, and Nexus as use cases and figure out what each of them needs to be
 * able to do
 *
 * - now what is really the difference between this and loading a component in plexus - custom
 * classloading capability - remote resolution of dependencies - do we want a model for sharing

Therefore, you really will want to review the remainder of this page in order to understand how to configure logging for your application.
