How do I create a Greengrass v2 deployment from on a config file using the Java SDK

Question

When using the AWS CLI, I can create a Greengrass v2 deployment using `aws greengrassv2 create-deployment --target-arn  --cli-input-json file://`

I already have the deployment file and would like to create the Greengrass v2 deployment programmatically using the Java SDK. 
`GreengrassV2Client`'s `createDeployment` method takes a `CreateDeploymentRequest` parameter but I didn't figure out how to parse a deployment config file into a `CreateDeploymentRequest` object.

Can you please advise on the idiomatic way to programmatically create a Greengrass v2 deployment from a deployment config file using the Java SDK?

I did find the answer eventually:

```
GetDeploymentResponse deployment = new ObjectMapper().readValue(deploymentJson, GetDeploymentResponse.serializableBuilderClass()).build();
```
