Hello Everyone,

We are solving a use case where we'd benefit from sending some connected data via logstash into neo4j, but we don't yet know how.  
We have tried to install:

> **[logstash-plugins/logstash-output-neo4j](https://github.com/logstash-plugins/logstash-output-neo4j)**
>
> A Logstash neo4j output. Contribute to logstash-plugins/logstash-output-neo4j development by creating an account on GitHub.

  
but it would not even appear in the list of installed plugins after running  
logstash-plugin list

Does anyone know about the development status of this plugin? Is it still maintained?  
If not, do you know of any alternatives please?

My Version is logstash6.3.2 and logstash-output-neo4j-2.0.5。  
I downloaded the gem from [https://rubygems.org/downloads/logstash-output-neo4j-2.0.5-java.gem](https://rubygems.org/downloads/logstash-output-neo4j-2.0.5-java.gem)  
and install it as

- append "gem "logstash-output-neo4j", "2.0.5", :path =\> "/usr/local/logstash/logstash-6.3.2/logstash-output-neo4j"" to Gemfile
- bin/logstash-plugin install --no-verify

after the second step，

```auto
Installing...
Installation successful

```

is printed on the screen。But，when I am starting logstash，I get

```auto

```

Thanks, all help is appreciated.
