./mvnw clean package fails with Java 13

[SSchwaiger]

I've cloned the code and ran ./mvnw clean package. Unfortunately, the compilation of the artefacts fails and therefore the Docker images cannot be built. Is there a special Java version dependency or am I missing sth. else in my configuration?

Suggestion: what if you add a multi-stage build to your Dockerfile to ensure the correct Java and tooling versions?

I reproduced the same behaviour using java 11 and 8

I'm currently working on updating the whole project to the latest Spring Boot and Spring Cloud versions and I assume this may fix the issue.

Building the project with OpenJDK 8 fixed it.
