Micronaut @Value does not get the environmental variable when running native image

Question

I've build a native image with graalvm and micronaut, but my native-image app cannot get the environmental variable using @Value annotation. When I try to run the app as jar, it works just fine.

@Singleton
public class WebComponentService {
    @Value("${config.adyen.merchantaccount}")
    private String merchantAccount;
}

This is the error I get

Message: Error setting field value: No field 'merchantAccount' found for type: example.micronaut.getOriginKeys.WebComponentService Path Taken: new GetOriginKeysController([WebComponentService webComponentService]) io.micronaut.context.exceptions.DependencyInjectionException: Failed to inject value for field [merchantAccount] of class: example.micronaut.getOriginKeys.WebComponentService

However, when I try to get the environmental variables like this, it works fine.

Map<String, String> environmentVars  = System.getenv();
String merchantAccount = environmentVars.get("CONFIG_ADYEN_MERCHANTACCOUNT");

This is how I run the native app

$ CONFIG_ADYEN_MERCHANTACCOUNT=CommercetoolsGmbHDE775 ./theNativeApp

Answer 1

The key you have used here @Value("${config.adyen.merchantaccount}") is different than environmentVars.get("CONFIG_ADYEN_MERCHANTACCOUNT");

Make sure they're the same
