class Gem::PackageTask
Create a package based upon a Gem::Specification
. Gem
packages, as well as zip files and tar/gzipped packages can be produced by this task.
In addition to the Rake targets generated by Rake::PackageTask, a Gem::PackageTask
will also generate the following tasks:
- “package_dir/name-version.gem”
-
Create a RubyGems package with the given name and version.
Example using a Gem::Specification
:
require 'rubygems' require 'rubygems/package_task' spec = Gem::Specification.new do |s| s.summary = "Ruby based make-like utility." s.name = 'rake' s.version = PKG_VERSION s.requirements << 'none' s.files = PKG_FILES s.description = <<-EOF Rake is a Make-like program implemented in Ruby. Tasks and dependencies are specified in standard Ruby syntax. EOF end Gem::PackageTask.new(spec) do |pkg| pkg.need_zip = true pkg.need_tar = true end
Attributes
