      @Mojo(name="detach-distributions",
            defaultPhase=VERIFY,
            threadSafe=true,
            aggregator=true)
      public class CommonsDistributionDetachmentMojo
      extends org.apache.maven.plugin.AbstractMojo

  The purpose of this Maven mojo is to detach the artifacts generated by the maven-assembly-plugin, which for the Apache Commons Project do not get uploaded to Nexus, and putting those artifacts in the dev distribution location for Apache projects.

    `private List<org.apache.maven.artifact.Artifact>` | `detachedArtifacts` This list is supposed to hold the Maven references to the aforementioned artifacts so that we can upload them to svn after they've been detached from the Maven deployment.
    `private String` | `distSvnStagingUrl` The subversion staging url to which we upload all of our staged artifacts.
    `private Boolean` | `isDistModule` A parameter to generally avoid running unless it is specifically turned on by the consuming module.

    - #### detachedArtifacts

          private final List<org.apache.maven.artifact.Artifact> detachedArtifacts

      This list is supposed to hold the Maven references to the aforementioned artifacts so that we can upload them to svn after they've been detached from the Maven deployment.

    - #### artifactSha512s

          private final Properties artifactSha512s

      A `Properties` of `Artifact` → `String` containing the sha256 signatures for the individual artifacts, where the `Artifact` is represented as: `groupId:artifactId:version:type=sha512`.

    - #### project

                     required=true)
          private org.apache.maven.project.MavenProject project

      The maven project context injection so that we can get a hold of the variables at hand.

    - #### workingDirectory

          @Parameter(defaultValue="${project.build.directory}/commons-release-plugin",
                     property="commons.outputDirectory")
          private File workingDirectory

      The working directory in `target` that we use as a sandbox for the plugin.

    - #### distSvnStagingUrl

          @Parameter(defaultValue="",
                     property="commons.distSvnStagingUrl")
          private String distSvnStagingUrl

      The subversion staging url to which we upload all of our staged artifacts.

    - #### isDistModule

          @Parameter(defaultValue="false",
                     property="commons.release.isDistModule")
          private Boolean isDistModule
