Overview

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:repackage: Rebuild the package files from scratch, even if they are not out of date.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

Constructor Details

.new(name = nil, version = nil) {|_self| ... } ⇒ `PackageTask`

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.
