As part of an automated build process I'd like to be able to install an ES plug-in which I obtain via Maven.
My idea is to unpack that Maven dependency (e.g. "org.elasticsearch.plugin:delete-by-query:2.0.0") and copy it into the plug-in directory of ES. The problem though is that this plug-in JAR (and several others I tried randomly) doesn't contain a plugin-descriptor.properties, causing ES not to start.
Where should I get this descriptor file from? Or are the plug-ins deployed as JARs to Maven Central not meant to be use in the way I described? Any help is appreciated.
