Azure, java sdk, Deploying with ARM template - failure to convert Parameter file

Question

I'm trying to write a java JUnit test that will deploy template-defined resource groups using the java-sdk for azure.

I came across a couple examples and followed them to create this code segment:

public void azurePoC() throws Exception {

    Azure azure = Azure.configure()
            .withLogLevel(LogLevel.BODY)
            .authenticate(new File("C:/somePath/credentials.azure"))
            .withDefaultSubscription();

    final ObjectMapper mapper = new ObjectMapper();
    JsonNode template = mapper.readTree(new File("C:/somePath/template.json"));

    Logger.report("template", template.toString());

    JsonNode params = mapper.readTree(new File("C:/somePath/parameters.json"));
    Logger.report("params", params.toString());

    azure.deployments()
            .define("myNewResource")
            .withNewResourceGroup("myNewResourceGroup", Region.US_WEST2)
            .withTemplate(template)
            .withParameters(params)
            .withMode(DeploymentMode.INCREMENTAL)
            .create();

    Logger.report("Request for deployment done.");
}

I have verified that the API allows me to lookup resources using azure.virtualMachines().list() method, therefore i conclude that my credentials are okay.

I am using one of the quick-start templates to for my PoC, just to see if i can deploy some resource.

My template.json file:

Whenever I run the application I am confronted with this exception:

For anyone who comes across this question.

Turns out the problem was the parameter file json syntax. The schema, parameters and version fields are redundant

this is the expected syntax using Azure Java SDK:

{
  "adminUsername": {
    "value": "ghuser"
  },
  "adminPassword": {
    "value": "GEN-PASSWORD"
  },
  "dnsLabelPrefix": {
    "value": "GEN-UNIQUE"
  }
}
