Docker – Logstash main class JvmOptionsParser not found / cannot load

I’ve been stuck on this problem for quite some time now, any help would be gladly appreciated.

So I have a docker compose containing Elastic Stack services, plus a Cassandra database.

I am trying to index data from the Cassandra database to ElasticSearch via Logstash, using a CassandraJDBC42.jar driver, which I am mounting via a docker volume.

Whenever I run the services docker compose up (Version-2 Docker Compose), everything runs smoothly except the Logstash service, it does not go up – and this is the error in the logs.

Using bundled JDK: /usr/share/logstash/jdk
Error: Could not find or load main class org.logstash.launchers.JvmOptionsParser 
Caused by: java.lang.ClassNotFoundException: org.logstash.launchers.JvmOptionsParser

And this is the Docker Compose Logstash service.

 logstash:
    image: logstash:7.17.18
    container_name: logstash
    # restart: always
    volumes:
      - logstash_data:/usr/share/logstash/data
      - ./cassandra-driver/:/usr/share/logstash/logstash-core/lib/jars # MOUNTING OF THE DRIVER
      - ./logstash/logstash.conf:/logstash_dir/logstash.conf
    command: logstash -f /logstash_dir/logstash.conf
    depends_on:
      - elasticsearch
    ports:
      - "9600:9600"
    environment:
      LS_JAVA_OPTS: "-Xmx256m -Xms256m"
    networks:
      - elastic

If I remove the mounting of the driver, everything runs smoothly.

Tried different versions of the images, the problem persists.

Tried a different driver, the same.

Tried running the container without the driver, getting inside, installing openjdk-11, mounting the driver again, still the same.
