Hello all,
I'm having a problem install the syslog output plugin to logstash 5.2.
After installing logstash using yum from a local rpm. I run this command: bin/logstash-plugin install logstash-output-syslog
However i get this output:
Validating logstash-output-syslog
Installing logstash-output-syslog
Error Bundler::InstallError, retrying 1/10
An error occurred while installing logstash-core-event-java (5.2.0), and Bundler cannot continue.
Make sure that `gem install logstash-core-event-java -v '5.2.0'` succeeds before bundling.

Error Bundler::InstallError, retrying 2/10

...
Until 10 tries then it dies. At this point logstash won't even start saying it cant find the syslog file.

I am having the same problem, I am trying to install the logstash-input-jmx plugin. Initially I thought that I was having a proxy/firewall problem, but I have retried with (linux and windows) and a completely exposed machine (no proxy/no firewall connection to the internet) I get the following errors:
