Motivation:
We should just use GitHub Actions for the CI
Modifications:
- Adjust docker / docker compose files
- Add different workflows and jobs to deploy and build the project
Result:
Don't depend on external CI services
Motivation:
OpenJDK15 was released, we should compile with it on the CI
Modifications:
Add docker-compose files to be able to compile with OpenJDK15
Result:
Compile with latest major JDK version
