quarkus: "DeploymentException: No config value of type [java.lang.String] exists for" in multi-module Gradle project

Describe the bug

I was wondering why I never was getting the ConfigProperties and ConfigProperty annotations working in my multi module project, now I found out that ConfigProperty fields cannot be loaded when the child/sub module has an application.properties file itself. It seems to collide or override the values of the application.properties file of the main application module.

Version

• Quarkus 1.4.1.Final

Actual behavior

To Reproduce Steps to reproduce the behavior:

I´ve created a reproducer with different usages of the ConfigProperties. Run it as it is and it will fail. Comment out the child module in the application/build.gradle and tests will work.

Reproducer: https://github.com/mklueh/quarkus-multi-module-config-property-issue

What is the strategy with submodule application.properties in general, does this work in any hierarchical depth? Are they merged with the main module or should they be ignored?

In my case I don´t need the submodule properties in my application, but my submodule has some tests itself which requires the properties file.
