Thanks - it works for standalone node!
But I have the second question: is there a possibility to use the plugin on classpath for embedded node?
It worked for version 1.x but stopped working for 2.x (I have some integration tests with this plugin with embedded node).
I've seen the topic about that (https://discuss.elastic.co/t/add-plugins-from-classpath-in-embedded-elasticsearch-client-node/36269/7) but haven't seen any suggestion how to deal with this problem.
Do you consider any way to support this case?
Thanks,
Przemyslaw
