Layer with directory cannot be set as parent of another Layer

[aalmiray]

Given the following configuration

layers:
  javafx:
    modules:
      - "org.openjfx:javafx-base:jar:mac:11.0.2"
      - "org.openjfx:javafx-controls:jar:mac:11.0.2"
      - "org.openjfx:javafx-graphics:jar:mac:11.0.2"
      - "org.openjfx:javafx-web:jar:mac:11.0.2"
      - "org.openjfx:javafx-media:jar:mac:11.0.2"
  core:
    modules:
      - "org.kordamp.tiles:modular-tiles-model:0.0.0"
      - "org.kordamp.tiles:modular-tiles-core:0.0.0"
      - "org.moditect.layrry:layrry-platform:1.0-SNAPSHOT"
      - "eu.hansolo:tilesfx:11.44"
    parents:
      - "javafx"
  plugins:
    parents:
      - "core"
    directory: plugins
  app:
    parents:
      - "plugins"
    modules:
      - "org.kordamp.tiles:modular-tiles-app:0.0.0"
main:
  module: "org.kordamp.tiles.app"
  class: "org.kordamp.tiles.app.Main"

Where the plugin layer is a parent of app.

When the plugins directory is empty and the application starts

Exception in thread "main" java.lang.IllegalArgumentException: Layer 'app': parent layer 'plugins' not configured yet
    at org.moditect.layrry.internal.LayersImpl.getParentLayers(LayersImpl.java:195)
    at org.moditect.layrry.internal.LayersImpl.run(LayersImpl.java:103)

    at org.moditect.layrry.launcher.LayrryLauncher.main(LayrryLauncher.java:34)

When the plugins directory has a layer such as

plugins
└── tile-clock-0.0.0
    └── tile-clock-0.0.0.jar

Exception in thread "main" java.lang.IllegalArgumentException: Layer 'app': parent layer 'tile-clock-0.0.0' not configured yet

    at org.moditect.layrry.Layrry.run(Layrry.java:41)
    at org.moditect.layrry.launcher.LayrryLauncher.launch(LayrryLauncher.java:48)
    at org.moditect.layrry.launcher.LayrryLauncher.main(LayrryLauncher.java:34)

Uh, oh, thanks for reporting. Definitely needs fixing; that said, I don't think you'd need the separate "app" layer, it should work if you move its contents to the "core" layer (like in the Vert.x example).
