Installing logstash plugins locally

Hi,

I am having trouble with latest logstash-coucdb plugin ie., when data is deleted from couchdb its not deleted in ES and an extra dummy sort of record gets created in ES as follows.

 `{

"index": "userindex",
"_type": "logs",
"_id": "b5a30ba6bcf908c1a3db884e68136d9e",
"_score": 1,
"_source": {
"@version": "1",
"@timestamp": "2015-09-23T19:40:01.172Z",
"tags": [
"users"
]
}
}
`

This was working in an earlier version of logstash-couchdb-changes plugin. I don't know its version as I was just running the following command to install plugin.

bin\plugin install logstash-input-couchdb_changes

As I understand this command would have downloaded the latest version of plugin at that time when it was working on it (probably couple of months ago). Now it might be downloading latest version of plugin and hence idelete is not working anymore.
(you can find this issue under github issue list of plugin as well: https://github.com/logstash-plugins/logstash-output-elasticsearch/issues/195#issuecomment-206170482).

Since this plugin is under active development, I wanted to try an earlier version of logstash-coucdb- changes plugin and see if it doesn't have this problem. Would it be right thing to do? and how can I download logstash-coucdb- changes plugin and install it locally? To install plugin locally, I am following instruction from page https://github.com/logstash-plugins/logstash-input-couchdb_changes/tree/master but seems like plugin is not install since didn't get any data.

Please help to resolve my issue.

Thanks,
Imad.
