These lines need to be restored to the Gemfile. The hawkins plugin is
needed for the incremental build and live reload feature
group :jekyll_plugins do
gem 'hawkins'
end
The bundled version of jekyll (3.7.2) requires ruby >= 2.1, but our build
machines use ruby 2.0. If we can't get the apache INFRA team to upgrade ruby,
we'll have to rework this.
The Gemfile.lock doesn't work with ruby 2.1 -- I get this error
ruby_dep-1.5.0 requires ruby version >= 2.2.5, which is incompatible
with the current version, ruby 2.1.10p492
but re-bundling fixes this. I think we should commit a Gemfile.lock file
that is compatible back to Ruby 2.1, if we determine we can get ruby 2.1 --
otherwise we'll have to roll back jekyll and then re-bundle with ruby 2.0.
This PR works fine on ruby 2.3 and 2.4. The latest stable release of rvm
doesn't yet support ruby 2.5, so I didn't test it.
