Hi Sujen, are the jars also listed in the plugin.xml?
That's required. The plugin-specific ivy.xml is only used at compile time to fetch the library and its dependencies and get the plugin compiled. At runtime all required libs have to be listed in the plugin.xml, e.g., https://github.com/apache/nutch/blob/master/src/plugin/parse-tika/plugin.xml This double work is not ideal and a frequent cause for errors but that's how it works right now.
