This might be a stupid question, but I can't seem to figure it out.

I'm trying to write a filter plugin for logstash and started by generating the default "Hello, world!" plugin and going through the basic development process. But I get stuck when running the _rspec_ testing process.

These are the steps I followed:

1. Downloaded logstash to my local machine from [https://www.elastic.co/downloads/logstash](https://www.elastic.co/downloads/logstash).

2. Ran the `bin/logstash-plugin generate --type filter --name new-plugin --path <path to a new repo I created>`

3. Figured out that I needed JRuby, so I installed _rvm_ then ran `rvm install jruby` and `rvm use jruby`.

4. Finally got `bundle install` working.

5. Woops! I still need _rspec_ so I `gem install rspec`.

6. Run `bundle exec rspec`, but I get the following result:

What could be causing this?

Thanks

What does the generated code look like?

I just updated the config files. I messed a bit with the \*\_spec.rb file, but didn't get it to work.

lib/logstash/filters/clean-job.rb

```
# encoding: utf-8
require "logstash/filters/base"
require "logstash/namespace"

# This filter will replace the contents of the default 
# message field with whatever you specify in the configuration.
#
# It is only intended to be used as an .
class LogStash::Filters::CleanJob < LogStash::Filters::Base

# Setting the config_name here is required. This is how you
# configure this filter from your Logstash config.
#
# filter {
# {
# message => "My message..."
# }
# }
#
config_name "clean-job"

# Replace the message with this value.
config :message, :validate => :string, :default => "Hello World!"

public
def register
    # Add instance variables 
end # def register

public
def filter(event)

    if @message
    # Replace the event message with our message as configured in the
    # config file.
    event.set("message", @message)
    end

    # filter_matched should go in the last line of our successful code
    filter_matched(event)
end # def filter
end # class LogStash::Filters::CleanJob

```

spec/filters/clean-job\_spec.rb

```
# encoding: utf-8
require_relative '../spec_helper'
require "logstash/filters/clean-job"

describe LogStash::Filters::CleanJob do
describe "Set to Hello World" do
    let(:config) do <<-CONFIG
    filter {
        clean-job {
        message => "Hello World"
        }
    }
    CONFIG
    end
    
    sample("message" => "some text") do
    expect(subject).to include("message")
    expect(subject.get('message')).to eq('Hello World')
    end
end
end

```
