Yesterday I had a problem when I tried to install logstash-output-zabbix on my logstash 5.2.
I used the recommended command "logstash-plugin install logstash-output-zabbix".But it failed with the error messgae
"Bundler::GemNotFound: Could not find gem 'logstash-output-zabbix (>= 0) java' in any of the gem sources listed in your Gemfile or installed on this machine."
I also tried the gem install logstash-output-zabbix,but the other error message appeared again.
ERROR: While executing gem ... (Gem::UnsatisfiableDependencyError)
Unable to resolve dependency: No match for 'logstash-core-plugin-api (<= 2.99, >= 1.60)' on this platform. Found: java
