I start nodes locally in unit tests, such as:

```
    hostNode = NodeBuilder.nodeBuilder().loadConfigSettings(false).clusterName("test.cluster").local(true).settings(
            ImmutableSettings.settingsBuilder()
            .put("index.number_of_shards", 1)
            .put("index.number_of_replicas", 1).build()
    ).node().start();
    elasticSearchClient = hostNode.client();

```

I want to use the attachment plugin. I can get it all to work when I start the stand-alone cluster and run the code in the java client.

Can I get the attachment plugin to work with the unit tests that start the node in memory as detailed above? If so, how?

Thanks

You just need to have the plugin jar file and its deps in the classpath. The  
plugins are also in maven repo, for the attachment plugin, you will also  
need Tika.
