Can't mount application.yaml into docker java 8 spring

Question

Can someone explain me, why it doesn't mounted and java don't read application.yaml?

This is my dockerfile:

FROM openjdk:17-jdk-slim
WORKDIR /app
COPY build/libs/Notify-2.0-all.jar app.jar
COPY src/main/resources/application.yaml resources/application.yaml
ENTRYPOINT ["java", "-jar", "app.jar"]

and this is docker compose

version: '3.7'
services:
  discord-bot-cyberdawn-boosty:
    image: discord-bot-v2
    volumes:
      - type: bind
        source: ./application.yaml
        target: /app/resources/application.yaml

I tried ${pwd} but it still doesn't work.

I also tried this

FROM openjdk:17
WORKDIR /app
COPY build/libs/Notify-2.0-all.jar app.jar
COPY src/main/resources/application.yaml /app/application.yaml
CMD ["java", "-jar", "app.jar", "--spring.config.name=application", "--spring.config.location=file:/app/application.yaml"]

version: '3.9'
services:
  test-bot:
    image: test-bot-v2
    volumes:
      - type: bind
        source: ${PWD}/application.yaml
        target: /app/application.yaml

and it's still doesn't work.

This doesn't work too:

docker run -v /home/bot-v2/cyberdawn/application.yaml:/app/application.yaml test-bot-v2
