Hi All

I'm want to use logstash-input-google-cloud-pubsub as input for logstash 2.2.2.  
All my tries to run it have failed so far.

Installing out of the box gives me an dependency error

> gcloud 0.6.1 requires Ruby 2.0

Installing in jruby compatability mode "JRUBY\_OPTS=--2.0" was success but failed at startup:

```
./bin/logstash -f /home/me/dev/proj/deployment/logstash/pipeline.conf

Installing version pinned to gcloud 0.5 succeeded. However trying to run it failed with the following:

```
./bin/logstash -f /home/me/dev/proj/deployment/logstash/pipeline.conf

```

Does Somebody already use it?  
Can you please share your experience of how do you run it exactly?

Thanks a lot,  
Ilya
