Cannot load such file -- ci/reporter/rake/rspec

[fifiteen82726]

ruby 2.1.10
Rails 3.2.22.5
I want to use ci_reporter to generate report xml, and then let jenkins publish error message.
I added this into gemfile

gem "ci_reporter"

Put following code into Rakefile

require 'ci/reporter/rake/rspec'
task :rspec => 'ci:setup:rspec'

Created a task file and put following code in lib/ci_report.rake

namespace :ci do
  task :all => ['ci:setup:rspec', 'rspec']
end

Then typed rake ci:all in terminal, but it threw this error

rake aborted!
LoadError: cannot load such file -- ci/reporter/rake/rspec

What did I miss?

A bit of a late answer, but according to 213e412 it was extracted to a gem, after searching for it, i found https://rubygems.org/gems/ci_reporter_rspec

This issue can probably be closed @nicksieger
