Quarkus trying to index lombok annotations

[Wouter684]

Describe the bug

I have a Quarkus application where I also use Lombok annotations, such as the @NonNull annotation. When using the quarkus-rest dependency in the application, I get the following warning when running mvn clean verify:

[WARNING] [io.quarkus.arc.processor.BeanArchives] Failed to index lombok.NonNull: Class does not exist in ClassLoader QuarkusClassLoader:Deployment Class Loader: PROD for lombok-nonnull-warning-0.0.1-SNAPSHOT@f4deb35

When removing the quarkus-rest dependency the warning disappears, but for obvious reasons the application no longer works as expected.

Expected behavior

The Lombok annotations should not be indexed, they are annotations and not beans.

Actual behavior

The Lombok annotations are being indexed as if they were beans, resulting in a warning being shown because they cannot be indexed.

How to Reproduce?

Reproducer: https://github.com/Wouter684/lombok-nonnull-warning

Steps to reproduce:

1. Open the application
2. Run mvn clean verify
3. Just before the BUILD SUCCESS message, the warning is displayed

When the dependency quarkus-rest is removed from the pom and mvn clean verify is run again, the warning is no longer shown. Of course the rest calls won't work anymore when starting the application and trying to send a call to the endpoint.
