I am trying to add plugin logstash-input-google-cloud-pubsub, When I built the gem file, It only support gem and ruby version\>2.2. I could install this plugin successfully using bin/plugin install.  
But when i run the test : bin/logstash -e 'input {google-cloud-pubsub {}}' --debug  
The error shows:

Compiled pipeline code:  
@inputs = []  
@filters = []  
@outputs = []  
@periodic\_flushers = []  
@shutdown\_flushers = []

```
      @input_google-cloud-pubsub_1 = plugin("input", "google-cloud-pubsub")

      @inputs << @input_google-cloud-pubsub_1

      @output_stdout_2 = plugin("output", "stdout", LogStash::Util.hash_merge_many({ "codec" => ("rubydebug") }))

      @outputs << @output_stdout_2

```

def filter\_func(event)  
events = [event]  
@logger.debug? && @logger.debug("filter received", :event =\> event.to\_hash)  
events  
end  
def output\_func(event)  
@logger.debug? && @logger.debug("output received", :event =\> event.to\_hash)  
@output\_stdout\_2.handle(event)

end {:level=\>:debug, :file=\>"logstash/pipeline.rb", :line=\>"38", :method=\>"initialize"}  
The error reported is:  
undefined local variable or method `cloud' for #<LogStash::Pipeline:0x20e18e70> (eval):7:in`initialize'  
org/jruby/RubyKernel.java:1079:in `eval' /opt/logstash/logstash/vendor/bundle/jruby/1.9/gems/logstash-core-2.1.0-java/lib/logstash/pipeline.rb:40:in`initialize'

What is the reason for this error since it already installed successfully.  
Is it a version issue for jruby1.9 in logstash. If that is the reason, is there a way to change the jruby version to \>2.2 in logstash.
