Hi,  
I'm having issues with installing this plugin. Here's the output from the install attempt. Many of the conflicts were duplicated and so have been removed for brevity:

```
Validating logstash-input-zeromq
Installing logstash-input-zeromq
Plugin version conflict, aborting
ERROR: Installation Aborted, message: Bundler could not find compatible versions for gem "logstash-core":
  In snapshot (Gemfile.lock):
    logstash-core (= 5.1.2)

  In Gemfile:
    logstash-core-plugin-api (>= 0) java depends on

Running `bundle update` will rebuild your snapshot from scratch, using only
the gems in your Gemfile, which may resolve the conflict.

Could not find gem 'logstash (< 2.0.0, >= 1.4.0) java', which is required by gem 'logstash-input-zeromq (>= 0) java', in any of the sources.

```

This isn't a system where I can install packages at will. And the impact of running bundler commands isn't clear either. I'd appreciate it if someone can help me move this forward?

Regards,  
David
