Can't get the project up and running
Hi! I'm just trying to follow the 'how to start' section of the README.md but I've faced a couple of problems.
My Java version is 11.0.15 (since the README says to use the 11 version).

When i run make up for bringing up the Docker environment, everything works fine as you can see in the following screenshot.

But when I run make build for building and creating the project JAR, the tests throw a bunch of errors as you can see in the following screenshot that don't allow me to continue with the build.

Am I doing something wrong or missing something? Any kind of feedback would be appreciated. 🙏🏻
Same issue in Archlinux operating system 
Can you take a look at this? 👀 @JavierCane @rgomezcasas
