How to create a syntetic bean for a singleton class not controlled by you

[bulldog98]

Assume we have some singleton class ala

public class SomeSingleton {
  public static synchronized SomeSingleton getInstance() {
    if (instance == null) {
          instance = new SomeSingleton();
    }
    return instance;
  }
}

I tried creating a syntetic in my custom extension like so

    // in a processor inside the deployment module
    @BuildStep
    @Record(STATIC_INIT)
    void makeSomeSingletonBean(
        final BuildProducer<SyntheticBeanBuildItem> syntheticBeanBuildItemBuildProducer
    ) {
        syntheticBeanBuildItemBuildProducer.produce(
            SyntheticBeanBuildItem.configure(SomeSingleton.class)
                .supplier(SomeSingleton::getInstance)
                .done()
        );
    }

Edit: after fixing that arc did not start the corresponding app in dev mode, I saw that the build step is not executed, so maybe a caching issue. I use gradle and have a multi module setup.

This somehow does not work. I always get an arc error that the bean is missing, what am I missing?

Found the problem, was that I misspelled the module name in the build.gradle for the deployment module.
