No such file to load -- org/apache/httpcomponents/httpclient/4.5/httpclient-4.5 (LoadError)

Hi,

I'm returning to ELK after a break for a few years. I've got this error when i start logstash up and include my remote elasticsearch node in the config on a very basic setup:

# bin/logstash -f conf.d/inputs.conf
#######START#########

The error reported is:

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 -- org/apache/httpcomponents/httpclient/4.5/httpclient-4.5 (LoadError)

Is anyone able to point me in the right direction please?

This is my logstash.conf file:

input {
  beats {
    port => 5044
  }
}

output {
  file {
    path => "/tmp/logs.%{+yyyy.MM.dd.HH}"
  }
  elasticsearch { hosts => ["https://elasticsearch_server:9200"] }
}

I have my ssl certificate to include but I'm not even getting that error yet. If I comment out the remote elasticsearch output, it works as expected and creates the file in /tmp.

Happy to supply more information and thanks for any help you can give me.

Regards
Dennis

To help me reproduce:

• what version of Logstash?

  bin/logstash --version
  

• what version of Java?

  java --version
  

• is JAVA_HOME set?

  echo $JAVA_HOME
  

• what version of the logstash-output-elasticsearch plugin?

  bin/logstash-plugin list --verbose logstash-output-elasticsearch

Hi Yaauie,

I'm sorry for the delay in getting back to you. I downloaded the Tar ball (instead of using the RPM) with all the component parts and set that up on my server. It's been working fine for me now for a couple of days and I think the issue may have been that that server has no internet access.
