Requirements

• Docker
• Docker Compose (comes with docker desktop for Windows users)
• Java 21 (For Windows users if your IDE doesn't manage JDK versions, maybe you will need to change manually by environment variables JAVA_HOME or Path), like the example below: , more information: https://www.happycoders.eu/java/how-to-switch-multiple-java-versions-windows/
• Gradle (maybe your IDE has already installed it for you)

How to run?

First, you will need to start the docker images by running docker-compose up at the root directory. This command will start two containers, PostgreSQL and RabbitMQ. After that, you are good to go, just start by your IDE or run ./gradlew bootRun at root directory.

Common beginners errors for Windows users

If you encounter some persisting errors trying to setup properly, probably the reasons are:

• Wrong Java Version at your Path or JAVA_HOME:
• Running at wrong order. The docker image need to be run first, the spring will fail on startup if it doesn't encounter the specified database available

To run the application using your IDE instead of the terminal, you will likely need to learn how to manage JDK versions within your IDE rather than changing environment variables IntelliJ example:
