Hello, I'm trying to setup a embedded elastic search cluster for integration tests, but I'm failing when I try to insert a painless script in this cluster, I opened this ticket because i thought might be a bug, but according @jasontedor is not a bug is probably is the missing painless plugin on my embedded cluster. so now the question how I install painless plugin on my cluster? how do I enable this, as far as I know it's a built in support.

more details here, [https://github.com/elastic/elasticsearch/issues/27275](https://github.com/elastic/elasticsearch/issues/27275)

I would be very thankful if someone help me.

It's not clear how you're building the embedded node, but if you use `ESSingleNodeTestCase` or `ESIntegTestCase` these do no include modules (which the `PainlessPlugin` is distributed as) by default. Additionally, if you construct a `Node` by hand, that too does not include the `PainlessPlugin`. Instead, you have to include it as a plugin for your node (which you can do by overriding certain methods on the test cases I mentioned, or when you construct the node). However, we do not support this, we do not do this anywhere in our testing infrastructure. Instead, when we want to test `Painless`, we build the zip distribution (which includes all modules by default) and start a standalone node which we then connect to with either the transport client or the REST clients. You can see examples of these in our standalone tests. I hope this helps clarify the situation.

Could you possibly link to one? (Using Gradle)
