I'm trying to install a plugin as bin/elasticsearch-plugin install <group_id>/<artifact_id>/ and I'm getting an "Uknown plugin" error. This used to work for me with older versions. Are there any changes around this installation way?
There used to be a lot of ways to specify plugin locations to install from. This was cleaned up in 5.0. The current syntax for maven uses the maven coordinates syntax, which would be:
bin/elasticsearch-plugin install groupId:artifactId:version
