Declare an InjectionPointInfo manually

[scrocquesel]

I have an extension that produce a synthetic bean only when an InjectionPointInfo in the BeanRegistrationPhaseBuildItem matches the produced bean type.
Now, I have another extension that would do the same thing for another bean and use the SyntheticBeanBuildItem.addInjectionPoint to inject the first bean.

Unfortunately, the first bean is not produced because the synthetic injection point is not discovered. Would it be possible to declare this InjectionPoint in a previous build step so the first bean can be produced with the same logic ?

I split the discovery and the requirement with an intermediate build item that other extensions can contribute to.

Still, if there is a shorter way of doing it, i'm still interested.

Unfortunately, you cannot define a synthetic injection point beforehand. Furthermore, the set of injection points accessible through the BeanDiscoveryFinishedBuildItem#getInjectionPoints() or SynthesisFinishedBuildItem#getInjectionPoints() is updated with synthetic injection points after all synthetic beans are registered.

I split the discovery and the requirement with an intermediate build item that other extensions can contribute to.

I'm not quite sure I understand this solution. Do I understand it correctly that the first extension produces a specific build item which signals that a synthetic bean was produced? In other words, a specific build item replaced the injection point check in another extension. If so then it's ok and I'm not aware of a better way.
