apigee-deploy-maven-plugin: How to create "Environments>Target servers" in Apigee Hybrid?
I'm currently trying to use https://github.com/apigee/apigee-deploy-maven-plugin/tree/hybrid

to create "Environments>Target servers" in Apigee Hybrid. However, no results.

Could someone please be so kind to suggest to me the correct ways of making such a task?

I utilize for this task config.json:

{
    "configurations": [
        {
            "name": "sandbox",

            "targets": [
                {
                  "name": "promotion.xml","tokens": [
                    {
                      "xpath": "/TargetEndpoint/HTTPTargetConnection/LoadBalancer/Algorithm","value": "RoundRobin"},{
                      "xpath": "/TargetEndpoint/HTTPTargetConnection/LoadBalancer/Server[1]/@name","value": "s1"},{
                      "xpath": "/TargetEndpoint/HTTPTargetConnection/LoadBalancer/Server[2]/@name","value": "s2"},{
                      "xpath": "/TargetEndpoint/HTTPTargetConnection/LoadBalancer/Server[3]/@name","value": "s3"},{
                      "xpath": "/TargetEndpoint/HTTPTargetConnection/LoadBalancer/MaxFailures","value": "10"},{
                      "xpath": "/TargetEndpoint/HTTPTargetConnection/LoadBalancer/RetryEnabled","value": "true"}
                  ]
                }              
              ]
        }]}

Good day, dear community,
thank you,
