Pointcut expression returning throws error

I have defined a pointcut like this 

@Pointcut("execution(* com.personal.services.Example.buildList(..))")
public void contextInterceptor() {
//pointcut identifier
}

I want to use it for afterReturning advice. How do I add the returning variable so that I can access it in my advice? 

@AfterReturning("contextInterceptor()")
public Object contextAdvice(JoinPoint jp, Object returnObj){
//process returnobj;
return returnObj;
}

I tried this but it gives me error

@Pointcut("execution(* com.personal.services.Example.buildList(..))",returning="returnObj")

You can do it all in one method like this:

@AfterReturning(
    pointcut = "execution(* com.personal.services.Example.buildList(..))",
    returning = "retVal"
)
public void afterReturning(JoinPoint joinPoint, Object retVal) {
    if (retObject != null) {
        logger.error("Returned object: " + retVal);
        logger.error("Returned type:   " + retVal.getClass().getName());
    }
}
