Running bundle exec jekyll serve on my local machine builds the site, and I can find the sitemap normally at localhost:4000/sitemap.xml (meaning it is definitely inside the _site directory).
However, after pushing the site to Github Pages, I can't find sitemap.xml, at least not in the root directory.
Gemfile:
# frozen_string_literal: true
source "https://rubygems.org"
gem 'github-pages', group: :jekyll_plugins
gem 'jekyll-sitemap'
gem "webrick", "~> 1.7"
_config.yml:
# Build settings
theme: jekyll-theme-midnight
plugins:
- jekyll-feed
- jekyll-remote-theme
- jekyll-sitemap
Just tested it in my project and it works. Try to move the gem into :jekyll_plugins group. Here is my Gemfile:
# If you want to use GitHub Pages, remove the "gem "jekyll"" above and
# uncomment the line below. To upgrade, run `bundle update github-pages`.
gem "github-pages", "~> 226", group: :jekyll_plugins
# If you have any plugins, put them here!
group :jekyll_plugins do
gem "jekyll-feed", "~> 0.12"
gem 'jekyll-sitemap'
end
But it also worked without putting it into the group, as described in the docs
