Maven Artifact Resolver Provider

 Maven Artifact Resolver Provider is a {{{/resolver/}Maven Artifact Resolver}} extension to support
 Maven POMs and local+remote repositories.

 Main component is <<<MavenRepositorySystemUtils>>>

* Logging Implementation

 Maven 3.1.0 ships bundled with {{{https://www.slf4j.org/api/org/slf4j/simple/SimpleLogger.html}SLF4J simple logger}} and since 3.5.0 {{{../maven-slf4j-provider/}Maven-customized <<<maven-slf4j-provider>>>}},
 but is ready to use other logging implementations: SLF4J is responsible for loading the implementation, referred to as
 {{{http://www.slf4j.org/manual.html#swapping}"SLF4J bindings"}}.

 * {{{./apidocs/org/apache/maven/plugin/logging/Log.html}<<<Log>>> interface}} provides easy logging for the goal.

 []

 A plugin is described in a {{{./plugin.html}<<<META-INF/maven/plugin.xml>>> plugin descriptor}},

       <<<versioning>>> element that gives data about snapshot (<<<snapshot>>>, <<<lastUpdated>>> and <<<snapshotVersions>>> list). Notice that a
       release artifact directory is not expected to provide metadata.

 []

 The following are generated from this model:

   * {{{./apidocs/index.html}Java sources}} with Reader and Writers for the Xpp3 XML parser, to read and write <<<maven-metadata(-*).xml>>> files,

 with its <<<DefaultArtifact>>> implementation ({{{./xref/org/apache/maven/artifact/DefaultArtifact.html}source}}).

 The jar file is executable and provides a little tool to display how Maven parses and compares versions:

+----+
$ java -jar maven-artifact-*.jar 3.2.4-alpha-1 3.2.4-SNAPSHOT 3.2.4.0
Display parameters as parsed by Maven (in canonical form) and comparison result:
