Fail to install Couchbase plugin for ElasticSearch

Question

I have CouchBase 2.5.0 enterprise installed with Elasticsearch 1.0.1. I want to install Couchbase plugin on Elasticsearch according to the instructions on http://www.couchbase.com/couchbase-server/connectors/elasticsearch, but it fails.

This is the error I get:

 groupId/artifactId/version   for community plugins (download from maven central or oss sonatype)

 username/repository          for site plugins (download from github master)

Message: Error while installing plugin, reason:

IllegalArgumentException: Plugin installation assumed to be site plugin, but contains source code, aborting installation.

Why is that ?

In the README of the downloaded master repo that it choked on, it says that they support Couchbase 2.2 (oddly not 2.5) and Elasticsearch 1.0.0 from the master repository, and not the 1.2.0 release of the plugin.

Try running it using their unlisted 1.3.0-SNAPSHOT (I found it via URL substitution from their README, which suggested 1.2.0):

bin/plugin -install transport-couchbase -url http://packages.couchbase.com.s3.amazonaws.com/releases/elastic-search-adapter/1.3.0/elasticsearch-transport-couchbase-1.3.0-SNAPSHOT.zip

Note: They do not yet explicitly list this release, but their pom.xml lists the version bump.
