TeamCity renderer

Empieza inspeccionando los renderizadores existentes y la ruta de salida de la CLI; después, lee la documentación enlazada de TeamCity service messages. Define cómo debe funcionar el uso de los renderizadores desde el código y la salida de la CLI, incluidos los requisitos de severidad y escaping. Se considera terminado cuando se puedan generar, transformar o escribir en stdout mensajes de inspección de TeamCity válidos.

It would be nice if there were a built-in TeamCity renderer, that can render TeamCity service messages, like for example

##teamcity[inspectionType category='openapi-diff' id='new-endpoint' name='New Endpoint' description='info -- New Endpoint']
##teamcity[inspection typeId='new-endpoint' file='build\openapi.json' message='info -- New Endpoint GET /showcase/v1/open/{id} - Query something totally open' SEVERITY='INFO']
##teamcity[inspection typeId='new-endpoint' file='build\openapi.json' message='info -- New Endpoint GET /showcase/v1/open/{open-id}/samples/{sample-id}/sub-samples/{sub-sample-id} - Query something else totally open' SEVERITY='INFO']
##teamcity[inspectionType category='openapi-diff' id='deleted-endpoint' name='Deleted Endpoint' description='error -- Deleted Endpoint']
##teamcity[inspection typeId='deleted-endpoint' file='build\openapi.json' message='error -- Deleted Endpoint GET /showcase/v1/whatever - Get whatever' SEVERITY='ERROR']
##teamcity[inspection typeId='deleted-endpoint' file='build\openapi.json' message='error -- Deleted Endpoint GET /showcase/v2/whatever - Get whatever else' SEVERITY='ERROR']
##teamcity[inspectionType category='openapi-diff' id='changed-operation' name='Changed Operation' description='Changed Operation']
##teamcity[inspection typeId='changed-operation' file='build\openapi.json' message='info -- Non-breakingly changed operation GET /showcase/v1/foo' SEVERITY='INFO']
##teamcity[inspection typeId='changed-operation' file='build\openapi.json' message='error -- Breakingly changed operation POST /showcase/v1/bar' SEVERITY='ERROR']
##teamcity[inspection typeId='changed-operation' file='build\openapi.json' message='error -- Breakingly changed operation POST /showcase/v1/bar/{bar-id}/baz/{baz-id}/boo' SEVERITY='ERROR']

In the CLI if enabled (or if TeamCity detected) this renderer should write to stdout.
When using via code, it should be a renderer like the others so that it can also be transformered or processed as necessary (like having one Gradle task that has it as output file and another that writes it to stdout so that the generation can be cached while the service messages will still be printed and thus processed).

The inspections can of course also be more fine-grained like for each specific change.
Or having more extensive messages which also support HTML (see linked docs).

Two things to keep in mind:

• While the docs list SEVERITY as custom attribute it should still be used as TeamCity indeed considers it to differentiate between error and non-errors
• Texts that could contain some special characters need a special escaping like this one:

  // | => || must be handled first. or we will
  // escape the previously added escape character
  text
      .replace("|", "||")
      .replace("'", "|'")
      .replace("\n", "|n")
      .replace("\r", "|r")
      .replace("[", "|[")
      .replace("]", "|]")
