In my setup, I have several ruby installations, but I only use one of them for my project. Therefore, the required gems are only installed in one of the ruby installations.

I did the following:

1) stop jenkins launch daemon and start it from the command line instead:
> launchctl unload /Library/LaunchDaemons/org.jenkins-ci.plist && JENKINS_HOME=/Users/Shared/Jenkins/Home /Library/Application\ Support/Jenkins/jenkins-runner.sh &>/var/log/jenkins/jenkins.log &
2) In Jenkins job configuration: Set rvm plugin to use ruby version "2.1.5"
3) In Jenkins job configuration: Use "build" -> "run shell command" and run a ruby command using a gem installed in version 2.1.5
4) run the Jenkins job

Expected result: Job should run properly

Actual result: Job fails due to missing gems. Sample output:

Exit status of command 'bundle install' was 1 instead of 0.
/Users/bygadmin/.rvm/rubies/ruby-2.1.5/lib/ruby/site_ruby/2.1.0/rubygems/dependency.rb:315:in `to_specs': Could not find 'bundler' (>= 0) among 106 total gem(s) (Gem::LoadError)
Checked in 'GEM_PATH=/Users/bygadmin/.rvm/gems/ruby-2.0.0-p643:/Users/bygadmin/.rvm/gems/ruby-2.0.0-p643@global', execute `gem env` for more information
from /Users/bygadmin/.rvm/rubies/ruby-2.1.5/lib/ruby/site_ruby/2.1.0/rubygems/dependency.rb:324:in `to_spec'
from /Users/bygadmin/.rvm/rubies/ruby-2.1.5/lib/ruby/site_ruby/2.1.0/rubygems/core_ext/kernel_gem.rb:58:in `gem'
from /Users/bygadmin/.rvm/gems/ruby-2.1.5/bin/bundle:22:in `<main>'

To identify what was wrong, I ran type rvm | head -1 in the shell command. Expected result: "rvm is a function". Actual result: "rvm is /Users/bygadmin/.rvm/bin/rvm".

My conlusion: rvm environment is not properly set up when running jenkins from command line.

Workarounds:

• It works when Jenkins is running as a launch daemon.
• It works if running rvm manually in the "run shell command" section:

  #!/bin/bash
  source ~/.rvm/scripts/rvm
  rvm use 2.1.5
