Can't launch Micronaut app using multiple layers #105

Open aalmiray opened 3 years ago

aalmiray commented 3 years ago

As reported at https://github.com/micronaut-projects/micronaut-core/issues/5095, a Micronat 2.4.0 demo application can be run with Layrry when a single layer is used

$ larry --layers-config https://raw.githubusercontent.com/aalmiray/micronaut-layrry-demo/main/layers-single.toml --verbose

Hi!

But breaks down when multiple layers are used

The multi layer configuration file looks like this

[layers.app]
  parents = ["micronaut"]
  modules = ["com.example:demo:0.1"]

[main]
  module = "com.example.demo"
  class = "com.example.DemoCommand"

The io.micronaut.configuration.picocli.PicocliRunner class is found in the io.micronaut.picocli:micronaut-picocli:3.2.0 dependency, defined in the micronaut layer, which is a parent of the app layer.
