Missing jruby gem for logstash

Question

I downloaded the latest version of logstash 1.4, and when I started it with the following configuration:

input {
  eventlog {    
  }
}
output { stdout {} }

I get this error:

D:\logstash-1.4.0\bin>logstash agent -f simpleConfig.config -l logs.log
Sending logstash logs to agent.log.

I think the win32ole jruby package is missing, but I don't know how to add it.

Thank you in advance for your help.

I have installed logstash-contrib-1.4.x.tar.gz.
I did not find the download link, so I copy the download link to logstash and add "-contrib" to the file name, for example: https://download.elasticsearch.org/logstash/logstash/logstash-contrib-1.4.2.tar. gz
This works great in my case. Installation will only unzip the file in home directoy and undo all files. Now it works.
