I have been working on a project A where I am adding aspects around AdminController for validating those urls when called but i have all the custom annotations in a separate repo B which i have added as an external jar in A as form of dependency.

Following are the files of project B where i have defined custom annotations.

Project B

@Retention(RetentionPolicy.RUNTIME)
@Target(ElementType.METHOD)
public @interface CustomAuth {

}

@Component
@Aspect
public class AuthAspect {

    @Before(value = "@annotation(com.company.services.annotations.CustomAuth)")
    public void doBefore(final JoinPoint joinPoint) {
          System.out.println("Validating the admin url");
    }

    @Around(value = "@annotation(com.company.services.annotations.CustomAuth)")
    public Object doAuthorize(final ProceedingJoinPoint proceedingJoinPoint) throws Throwable {
        System.out.println("During this");
        long start = System.currentTimeMillis();
        Object proceed = proceedingJoinPoint.proceed(); // Continue with the method execution
        long executionTime = System.currentTimeMillis() - start;
        System.out.println(proceedingJoinPoint.getSignature() + " executed in " + executionTime + "ms");
        return proceed;
    }
}

pom.xml of B

    </build>

Below are the set of files i have in project A where AdminController is there.

AdminController.java

@RestController
@RequestMapping("/{version}/admin")
public interface AdminController {

    @CustomAuth
    @GetMapping(value = "/node/status",
            produces = {MediaType.APPLICATION_JSON})
    void getStatus();

  }

Main SpringBoot file

@Configuration
@SpringBootApplication
@EnableAspectJAutoProxy
@ComponentScan(value = {"com.company"})
@EntityScan({"com.company"})
public class SpringBootApplication {
    public static void main(String[] args) {
        SpringApplication.run(SpringBootApplication.class, args);
    }
}

With this configuration, I am not able to do load time weaving for aspect on custom annotation. Any idea why this is not working or what i am missing here?
