`compare_versions': undefined method `[]' for nil:NilClass (NoMethodError)

[Ashish Sharma]

Hello,

I am new to ruby and to this gem.

trying to automate some jenkins builds, so i wrote up a quick script to launch a demo job. The job works fine on my test jenkins server, but is failing with the subject error on the production one.

I can see the job is being triggered, so its probably something when querying for status or something. Jenkins version is 1.532.2.2 (Jenkins Enterprise by CloudBees 13.11)

Here is the script

require 'jenkins_api_client'

begin

@client = JenkinsApi::Client.new(:server_url => 'http://prod_jenkins:8080/jenkins/job/Teams/job/MyTeam/',

:username=> ARGV[0],

:password=> ARGV[1],

:log_level=> Logger::DEBUG

)

puts @client.job.list_all

puts @client.get_jenkins_version

puts "Starting job sequence"

completed=false

on_progress = lambda do |max,curr,count|

puts " maxwait #{max} current_wait #{curr} current_count #{count}" 

end

on_completed = lambda do |build_number,cancelled|

puts "done build #{build_number} cancelled #{cancelled}"

completed = true

 end

opts = {'build_start_timeout' => 300,

'cancel_on_build_start_timeout' => true,

'progress_proc' => on_progress ,

'completion_proc' => on_completed

}

@client.job.build("script_test_job", {}, opts)

puts "Job launched, waiting now"

sleep 2 until completed

end

Ashish,

I think i know what the problem could be. I believe it is due to the version number having 4 parts in it. I'll look into that more later this weekend.

Hi Kannan,

wondering if you got a chance to look into it ?

thanks
