Due to what I assume to be classloader shenanigans, the generated Gizmo classes cannot access annotations on fields/methods at Quarkus build time. An escape hatch was added to SolverConfig for those users that need to build a Solver or related components at Quarkus build time.

There was a problem hiding this comment.
As discussed on Slack, we should make sure the SDK can access the constraint metamodel through the build item which already exists.
The build item probably needs to do the same hack that the PR already uses. The benefit is though that the build item need not do this publicly and therefore the method on solver config need not exist.
(Arguably, we should do something similar with the gizmo stuff on solver config as well. We have access to internals, we should just push this information through wherever we need this, without bothering the user with this nasty impl detail.)
