Maven Clean Plugin
  The Maven Clean Plugin is a plugin that removes files generated at build-time
  in a project's directory.

clean:clean
  Goal which cleans the build.
  This attempts to clean a project's working directory of the files that were
  generated at build-time. By default, it discovers and deletes the directories
  configured in project.build.directory, project.build.outputDirectory,
  project.build.testOutputDirectory, and project.reporting.outputDirectory.

  Files outside the default may also be included in the deletion by configuring
  the filesets tag.

  Available parameters:

    excludeDefaultDirectories (Default: false)
      Disables the deletion of the default output directories configured for a
      project. If set to true, only the files/directories selected via the
      parameter filesets will be deleted.
      Expression: ${clean.excludeDefaultDirectories}

    failOnError (Default: true)
      Indicates whether the build will continue even if there are clean errors.
      Expression: ${maven.clean.failOnError}

    filesets
      The list of file sets to delete, in addition to the default directories.
      For example:
      <filesets>
        <fileset>
          <directory>src/main/generated</directory>
          <followSymlinks>false</followSymlinks>
          <useDefaultExcludes>true</useDefaultExcludes>
          <includes>
            <include>*.java</include>
          </includes>
          <excludes>
            <exclude>Template*</exclude>
          </excludes>
        </fileset>
      </filesets>

    followSymLinks (Default: false)
      Sets whether the plugin should follow symbolic links while deleting files
      from the default output directories of the project. Not following symlinks
      requires more IO operations and heap memory, regardless whether symlinks
      are actually present. So projects with a huge output directory that
      knowingly does not contain symlinks can improve performance by setting
      this parameter to true.
      Expression: ${clean.followSymLinks}

    retryOnError (Default: true)
      Indicates whether the plugin should undertake additional attempts (after a
      short delay) to delete a file if the first attempt failed. This is meant
      to help deleting files that are temporarily locked by third-party tools
      like virus scanners or search indexing.
      Expression: ${maven.clean.retryOnError}

    skip (Default: false)
      Disables the plugin execution.
      Expression: ${clean.skip}

    verbose
      Sets whether the plugin runs in verbose mode. As of plugin version 2.3,
      the default value is derived from Maven's global debug flag (compare
      command line switch -X).
      Expression: ${clean.verbose}
