Quarkus ConfigItems - how to use no prefix?

[rsshah]

I have a requirement that I need an extension's config property to be named exactly myProperty in my application config. When I use a @ConfigRoot and @ConfigItem class as such:

@ConfigRoot(prefix="", phase=ConfigPhase.RUN_TIME, name="")
public class MyConfig {
    /**
     * javadoc
     */
    @ConfigItem(name= "myProperty")
    String myProperty;
}

Quarkus prefixes a . and looks for .myProperty in configuration instead, throwing this error:

One or more configuration errors have prevented the application from starting. The errors are:
  - SRCFG00014: The config property .myProperty is required but it could not be found in any config source

How do I just tell it what property name I want it to use, without it trying to be too smart?

I've found myself just ending up referencing the ConfigProvider in my config objects to work around this, which seems like an anti-pattern, but I don't know the idiomatic way to do what I want in Quarkus. I'm still learning the framework.

@ConfigRoot(prefix="", phase=ConfigPhase.RUN_TIME, name="")
public class MyConfig {
    public String getMyProperty() {
        return ConfigProvider.getConfig().getValue("myProperty", String.class);
    }

// other potential configs...
}

Please, use @ConfigMapping and interface-based configs: https://quarkus.io/guides/writing-extensions#configuration.

You can use @WithName to override the configuration name, and it should work with empty prefixes.
