Alias to enum does not work

[meloniasty]

Hi,
I have defined alias for enum in swagger.yml :

  components:
    schemas:
      Colors:
      type: string
      enum: &COLORS
        - black
        - white
        - red
        - green
        - blue

but it does not recognised properly in routes file.
routes:

###
#  summary: Get logged user
#  parameters:
#   - name: category_id
#     in: query
#     type: integer
#     required: false
#   - name: product_type
#     in: query
#     type: string
#     enum: *COLORS
#   - name: date
#     in: query
#     type: string
#     pattern: '^\d{2}-\d{2}-\d{4}$'
#     required: false
#     description: Date in format dd-MM-yyyy
#  responses:
#    200:
#       description: json with provision table definitions
###
GET        /users        controllers.HomeController.index

I'm getting exception when use sbt command swagger or run:

[play-swagger-alias] $ run

seems that generator does not know alias

I pushed example project with bug here: https://github.com/meloniasty/play-swagger-alias
