We use an embedded Elasticsearch within our Java integration tests, but upon upgrading to Elasticsearch 2 we are getting the following error on our Template Queries:

[{"type":"illegal\_argument\_exception","reason":"script\_lang not supported [mustache]"}]

Template Query works fine on a stand-alone server.

Our maven dependencies have been set up with:

```auto
groupId: org.elasticsearch
artifactId: elasticsearch
version: 2.1.1

```

The code to start the embedded server looks more or less like this:

```auto
settings = Settings.settingsBuilder()
    .put("path.home", dataDir.toString)
    .put("cluster.name", clusterName)
    .put("http.enabled", "true")
    .put("http.port", httpPort)
    .put("transport.tcp.port", PortFinder.random())
    .build();

nodeBuilder().local(true).settings(settings).build().start()

```

Anyone else having this sort of problem?

I can reproduce your issue.

I fixed it by adding this to my project:
