Sean Busbey created YETUS-305:
---------------------------------

             Summary: site building should check for minimum git version
                 Key: YETUS-305
                 URL: https://issues.apache.org/jira/browse/YETUS-305
             Project: Yetus
          Issue Type: Improvement
          Components: website and documentation
    Affects Versions: 0.1.0, 0.2.0
            Reporter: Sean Busbey
            Priority: Minor


When building per-release documentation, we do some git magic:

{code}
  puts "\tcloning from tag."
  `(cd "#{output}" && git clone --depth 1 --branch "#{version}" --single-branch 
-- "#{GITREPO}" "build-#{version}") >"#{output}/#{version}_git_checkout.log" 
2>&1`
  unless $?.exitstatus == 0
    abort("building docs failed to for #{version}.")
  end
{code}

This doesn't work with older versions of git:

{code}
busbey2-MBA:asf-site-src busbey$ rvm use 2.2.0@yetus-site
Using /Users/busbey/.rvm/gems/ruby-2.2.0 with gemset yetus-site
gbusbey2-MBA:asf-site-src busbey$ git --version
git version 1.7.10.2 (Apple Git-33)
busbey2-MBA:asf-site-src busbey$ bundle exec middleman build
Building docs for release 0.1.0
        cleaning up output directories in ../target
        cloning from tag.
building docs failed to for 0.1.0.
busbey2-MBA:asf-site-src busbey$ source ~/.bashrc
busbey2-MBA:asf-site-src busbey$ git --version
git version 2.1.0
busbey2-MBA:asf-site-src busbey$ bundle exec middleman build

   identical  
publish/documentation/in-progress/audience-annotations-apidocs/stylesheet.css
   identical  publish/documentation/0.1.0/audience-annotation
   ....SNIP....
{code}

we should check the git version and bail early.
