Cannot install plugin gelf on logstash5

[gallart]

• Version: logstash-5.0.2
• Operating System: Gentoo Linux

Installation does not work :

./bin/logstash-plugin install logstash-output-gelf
Validating logstash-output-gelf
Installing logstash-output-gelf
Error Bundler::InstallError, retrying 1/10
An error occurred while installing logstash-core-event-java (5.0.1), and Bundler cannot continue.
Make sure that `gem install logstash-core-event-java -v '5.0.1'` succeeds before bundling.

Any idea what I'm missing ?
