        "c": "dev"
    },
    "list": "${LIST_TEST}",

... with base.json

{
    "__variables": {
        "PARAM_BASE_PATH": "/app/${ENVIRONMENT}",
        "LIST_TEST": [
            1,
            2,
            3
        ],
        "LIST_MAP": {
            "a": 44
        }
    },
    "environment": [
        {
            "name": "ENVIRONMENT",
            "value": "${ENVIRONMENT}"
        },
        {

        }
    ],
    "mergemap": {
        "a": "base",
        "b": "base"
    }
