I'm currently trying to install the JDBC river on an 1.5 elasticsearch instance.
When running:
/bin/plugin --install jdbc --url http://xbib.org/repository/org/xbib/elasticsearch/plugin/elasticsearch-river-jdbc/1.5.0.0/elasticsearch-river-jdbc-1.5.0.0.zip
I obtain the following error:
Error: Could not find or load main class org.elasticsearch.plugins.PluginManager
Do you have any idea of the origin of the problem?
EDIT: I tried
bin/plugin
And get the same error, so it's not related to the url.
EDIT2: I'm using Windows.
