Intercepting aspect for custom annotion

I am writing a library/sdk which can intercept any methods which are annotated with a custom annotation @Monitor. The code works somewhat like this

@Monitor
public void methodA(String test)

And the aspect which intercepts this has this pointcut expression

@After("execution(@com.packageA.Monitor * *(..))")
public void intercept(final JoinPoint joinPoint){
...}

This code works fine when I describe the aspect in the same package as the methodA. However if I create a separate library and define the aspect in that its not able to intercept the methodA . Any help?

EDIT

In response to @Bond's comment

@Component
@Target(value = {ElementType.METHOD, ElementType.TYPE})
@Retention(value = RetentionPolicy.RUNTIME)
public @interface Monitor {

}

Spring versions: spring-context - 4.1.7.Release aspectj - 1.6.5 The crux of the problem is that the annotation wont be used in the same project. After compilation it will be used in a different project all together.

EDIT2

The 2nd project i.e the one from which this aspect should be intercepting is compiled using aspectj maven plugin

You need to update the pointcut to @annotation(com.x.y.z.Monitor). (correct the package name accordingly)

Thus your aspect should look something like below 

@After("@annotation(com.x.y.z.Monitor)") 
public void intercept(final JoinPoint joinPoint){
    ...
}

Have a look at examples for reference about various pointcut expressions available. Also read this in case advise accepts argument(s)
