custom.dependencies.ignore is not working properly

[Brawdunoir]

Hello, I am observing a strange behavior with the custom.dependencies.ignore array.

Take this skaffold config:

apiVersion: skaffold/v4beta12
kind: Config
metadata:
  name: myproject
build:
  artifacts:
    - image: myimage
      context: ./test-build-avoidance
      custom:
        buildCommand: ./build.sh myimage
        dependencies:
          paths:
            - ./src/*
          ignore:
            - ./src/ignore/*
  tagPolicy:
    dateTime: {}
  local:
    push: true

And this structure:

test-build-avoidance/
├── build.sh
└── src
    ├── ignore
    │   └── tobeignored
    └── randomcode

When I run this command skaffold build --cache-file skaffold.cache -d myregistry:

• First time it builds the app normally, push the image and puts digests in skaffold.cache file
• Second time it does not build, but only find and tag the first image with the new tag
• Now I change something in the file tobeignored
• Third time the build is triggered again but it shouldn’t be from my understanding

This is the output of skaffold diagnose. I notice that even with this command the file tobeignored is counted.
