Couldn't find any output plugin named 'elasticsearch'

Hi Team,

I get logs from scribe on 1463 port to log stash, and I have installed logstash-output-elasticsearch as well, when I try run log stash with both the paths its not detecting the output path; below is the command I am running

bin/logstash agent -p /opt/wapp/logstash/logstash-scribeinput -p /opt/wapp/logstash/vendor/bundle/jruby/1.9/gems/logstash-output-elasticsearch-2.1.2-java/lib -f /opt/logstash/conf/logstash-scribe.conf

however I am getting the below error

Error: Couldn't find any output plugin named 'elasticsearch'. Are you sure this is correct? Trying to load the elasticsearch output plugin resulted in this error: load error: manticore -- java.lang.NoSuchFieldError: INSTANCE

I did some digging and found that it is taking only one path like either scribe input path or elastic output path while running, i.e if I remove scribe path it says scribe plugin missing and if I remove elastic search output it says elastic search plugin missing, if I keep both it says elastic plugin missing.

Please guide me on how I can point both the paths without facing any issues.
