Check gem dependencies of ruby apps and generate report.

At XING we use this gem in combination with jenkins to automatically check on gem versions across our many projects.

gem install gem_version_check

Use the Github project name:

gem_version_check fdietz/team_dashboard

Use any url to a Gemfile.lock:

gem_version_check https://raw.github.com/fdietz/team_dashboard/raw/master/Gemfile.lock

Use --host option if you use Enterprise Github:

gem_version_check fdietz/team_dashboard --host github.mycompany.com

Use --only option if you want to specify the list of gems

gem_version_check fdietz/team_dashboard --only activesupport,rspec

Use --output-format if you want different formats

gem_version_check fdietz/team_dashboard --output-format=json

Example command: gem_version_check fdietz/team_dashboard --only activesupport,rspec

Output:

Project: fdietz/team_dashboard
 * activesupport:  != 3.2.8
 * rspec:  != 2.11.0
