Getting No such Method Exception When trying export entire index

[bhattiprolup]

Hi
I am new to this utility , I installed the version 1.5.2 of the plugin and my Elastic Search version is 1.5.2 .
When trying to export the entire index :

curl -XPOST localhost:9200/my_search_index/_export

I get the following error :

{"error":"NoSuchMethodError[org.xbib.io.archive.ArchiveService.newSession(Ljava/nio/file/Path;Lorg/xbib/io/BytesProgressWatcher;)Lorg/xbib/io/archive/ArchiveSession;]","status":500}

is there anything i am missing here ?

Note : I restarted the node after installing the plugin.
