ModuleNotFoundException: org.keycloak.keycloak-admin-client" in Docker container

I tried the following (I'm a Java noob):

I checked out this repo.

Then I ran

docker run -it --rm --name my-maven-project -v "$(pwd)":/usr/src/mymaven -w /usr/src/mymaven maven:3.3-jdk-8 mvn clean install

I created an empty folder where I copied the file keycloak-magic-link-0.2-SNAPSHOT.jar from the target folder into. Next, I created a docker-compose.yml file inside the same folder.

version: "3"

services:
  keycloaktestdb:
    container_name: keycloaktestdb
    image: postgres:14
    ports:
      - 5434:5432
    environment:
      - POSTGRES_DB=keycloak
      - POSTGRES_USER=keycloak
      - POSTGRES_PASSWORD=password
  idptest:
    image: quay.io/keycloak/keycloak:16.1.1
    container_name: idptest
    depends_on:
      - keycloaktestdb
    ports:
      - 8081:8080
    environment:
      - DB_VENDOR=POSTGRES
      - DB_ADDR=keycloaktestdb
      - DB_DATABASE=keycloak
      - DB_USER=keycloak
      - DB_SCHEMA=public
      - DB_PASSWORD=password
      - KEYCLOAK_USER=admin
      - KEYCLOAK_PASSWORD=admin
    volumes:
        - ./keycloak-magic-link-0.2-SNAPSHOT.jar:/opt/jboss/keycloak/standalone/deployments/keycloak-magic-link-0.2-SNAPSHOT.jar

As you can see, I've mapped the keycloak-magic-link-0.2-SNAPSHOT.jar into the deployments folder.

Next I ran docker compose up -d.

docker logs idptest gave me these errors:

Did I do something wrong?
