A small wrapper program named ec-jruby is installed as part of the CloudBees CD/RO tools. You can use it to run JRuby scripts.

Default Location of ec-jruby

  • The default location for ec-jruby on Linux is

  • The default location for ec-jruby on Windows is

    C:\Program Files\CloudBees\Software Delivery Automation\bin\ec-jruby

CloudBees CD/RO automatically adds ec-jruby to your path.

Running ec-jruby

To run ec-jruby :

  1. Set COMMANDER_HOME and COMMANDER_DATA as environment variables.

  2. Enter ec-jruby <yourJRubyOptions> <JRubyScriptName>.rb on the command line.

There is no language-specific binding for JRuby. Use the REST API to communicate with the CloudBees CD/RO server.

Example of a JRuby Script

require 'net/https'
require 'cgi'

uri = URI.parse("https://" + ENV["COMMANDER_SERVER"] + ":" +
ENV["COMMANDER_HTTPS_PORT"] + "/rest/v1.0/projects")

http =, uri.port)
http.use_ssl = true
# Only set VERIFY_NONE for development / testing
http.verify_mode = OpenSSL::SSL::VERIFY_NONE

request =

cookie ='sessionId',ENV["COMMANDER_SESSIONID"])
request['Cookie'] = cookie.to_s

response = http.request(request)

puts response.body
