# class Rake::PackageTask

Create a packaging task that will package the project into distributable files (e.g zip archive or tar files).

The PackageTask will create the following targets:

`:package`

  Create all the requested package files.

`:clobber_package`

  Delete all the package files. This target is automatically added to the main clobber target.

`:repackage`

  Rebuild the package files from scratch, even if they are not out of date.

`"package_dir/name-version.tgz"`

  Create a gzipped tar package (if need_tar is true).

`"package_dir/name-version.tar.gz"`

  Create a gzipped tar package (if need_tar_gz is true).

`"package_dir/name-version.tar.bz2"`

  Create a bzip2'd tar package (if need_tar_bz2 is true).

`"package_dir/name-version.zip"`

  Create a zip package archive (if need_zip is true).

Example:

    Rake::PackageTask.new("rake", "1.2.3") do |p|
      p.need_tar = true
      p.package_files.include("lib   /*.rb")
    end

### Public Class Methods

new(name=nil, version=nil) { |self| ... } click to toggle source

Create a Package Task with the given name and version. Use `:noversion` as the version to build a package without a version or to provide a fully-versioned package name.

    # File lib/rake/packagetask.rb, line 86
    def initialize(name=nil, version=nil)
      init(name, version)
      yield self if block_given?
      define unless name.nil?
    end

### Public Instance Methods

define() click to toggle source

Create the tasks defined by this task library.

    # File lib/rake/packagetask.rb, line 108
    def define
      fail "Version required (or :noversion)" if @version.nil?
      @version = nil if :noversion == @version

      task :clobber_package do
        rm_r package_dir rescue nil
      end

      task clobber: [:clobber_package]
