Spring BeanCreationException: Unexpected exception during bean creation

I have a notification library (written in Spring Boot, gradle, Java) which has a Service class (an interface) and an Implementation class (which extends the Service class and overrides the methods).

Service interface:

public interface NotificationService {
    void sendNotification(String title, String message, List<String> ids);

Implementation class:

@Component
public class NotificationServiceImpl implements NotificationService {
    private String notificationServiceURL;

    public NotificationServiceImpl(@Value("${notificationService.url}") String notificationServiceURL) {
        this.notificationServiceURL = notificationServiceURL;
    }

    public void sendNotification(String title, String message, List<String> employeeIds) {
        // Some functionality
    }
}

Application.yaml

notificationService:
  url: "someURL"

I have packaged this library as a JAR and imported in some project which is also Spring boot project.

Now, in the main class, I added Component Scan for the path where the imported library classes are:

@ComponentScan({"com.abchealth.xyz.red", "com.abchealth.xyz.red.service", "com.abchealth.xyz.red.service.serviceImpl"})
public class SecondProject {
    public static void main(String[] args) {
        SpringApplication.run(SecondProject.class, args);
    }
}

Then in one of the inner classes, I created an object of NotificationService

@Slf4j
@Component
@StepScope
public class SomeInnerClass implements Tasklet {

    @Autowired
    NotificationService notificationService;

    // some code

When I run the application, it gives me this error:

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'notificationServiceImpl' defined in URL [jar:file:/Users/usera/.gradle/caches/modules-2/files-2.1/com.abchealth.xyz.red/notification-lib/1.0.0-12/f973790603b7c261b2f6a693e83ca3e8f3f021de/notification-lib-1.0.0-12-scan.jar!/com/abchealth/xyz/red/service/serviceImpl/NotificationServiceImpl.class]: Unexpected exception during bean creation; nested exception is java.lang.IllegalArgumentException: Could not resolve placeholder 'notificationService.url' in value "${notificationService.url}"
	at org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.createBean(AbstractAutowireCapableBeanFactory.java:529) ~[spring-beans-5.2.8.RELEASE.jar:5.2.8.RELEASE]

Note: If I test this directly in Notification library by creating an object of NotificationService, it works just fine! The issue is when it is being imported in other project.

You need add notificationService.url property to your SecondProject's application.yml
