Legacy Artifact Handlers Reference

  Maven 3 artifact handlers (see {{{../maven-artifact/apidocs/org/apache/maven/artifact/handler/ArtifactHandler.html} API}})
  define for each {{{../maven-model/maven.html#class_dependency}dependency type}} information on the artifact
  (classifier, extension, language) and how to manage it as dependency (add to classpath, include dependencies).

            Other values define only the prefix of classes/resources being exposed. Their binary name must be equal to the prefix or starting with the prefix (followed by "." or "$").
