Core: Inheritance in Pebble templates

[slandelle]

From mailing list:

I'm using Pebble templates to generate the request bodies I'm using for my calls, now one of the main features of Pebble is that it supports inheritance but I can't get it to work. I have a parent template search-filter.peb

{
  "first": 0,
  "rows": 10,
  "filters": {
    {% block additionalFilter %} {% endblock %}
  }
}

and a child template

{% extends "search-filter.peb" %}

{% block additionalFilter %}
      "status": "PENDING"
{% endblock %}

and I import this into my call like this:

  val search: ChainBuilder = exec(http("Search")
    .post("/my-service/search")
    .body(PebbleFileBody("child-filter.peb")).asJson
    .headers(Config.requestHeaders)
  )

=========================
HTTP request:
POST my-service/asset-purchases/search
Connection: keep-alive

DNT: 1

=========================

do I need to do something else to get this inheritance to work? Or refer to the path in a different way? All templates are just located under the /main/resources folder.
