Hello-  
I cloned many logstash plugins and executed the specs, but I get the jars dependency issues.

```auto
An error occurred while loading ./spec/unit/outputs/elasticsearch_spec.rb.
Failure/Error: require "logstash/devutils/rspec/spec_helper"

RuntimeError:

  	you might need to reinstall the gem which depends on the missing jar or in case there is Jars.lock then resolve the jars with `lock_jars` command

  no such file to load -- com/fasterxml/jackson/module/jackson-module-afterburner/2.7.4/jackson-module-afterburner-2.7.4 (LoadError)

```

Could someone help me out with this.
