hi all;

I'm very new to elasticsearch, and I wanted to install fsriver and mapper-attachments but when i write a command " bin/plugin -install fr.pilato.elasticsearch.river/fsriver/0.2.0" i get error that "Couldn't find or load main class org.elasticsearch.plugins.PluginManager".

I found PluginManager java file but i seriously don't know where do I place that java file. Pls help , tnx 🙂
