Spring Boot Application with Spring Batch not Running Jobs

I have spring boot application I created from here at spring's site. I'm tampering with it and have basically duplicated it into two jobs, as I'm creating a bigger application that will be structured this way. Nothing is running though and I know it's most likely something small I'm missing.

If I stuff everything into one package just like the tutorial, it works fine, but if I extract the Application.java out into its own package, it seems to not acknowledge the other two packages. Even with passing through -Dspring.batch.job.names=myJob.

This is all there is to my main class:

@SpringBootApplication
@EnableBatchProcessing
public class Application implements CommandLineRunner {

    public static void main(String[] args) throws Exception {
        SpringApplication.run(Application.class, args);
    }

    @Override
    public void run(String... arg0) throws Exception {
        System.out.println("Running...");

    }
}

The project structure looks like:

\---main
    +---java
    |   +---app
    |   |       Application.java
    |   |       
    |   +---job1
    |   |       Job1BatchConfiguration.java
    |   |       Job1JobCompletionNotificationListener.java
    |   |       Job1Person.java
    |   |       Job1PersonItemProcessor.java
    |   |       
    |   \---job2
    |           Job2BatchConfiguration.java
    |           Job2JobCompletionNotificationListener.java
    |           Job2Person.java
    |           Job2PersonItemProcessor.java
    |           
    \---resources
            sample-data-2.csv
            sample-data.csv
            schema-all.sql

Again, if I put Application.java into either the job1 or job2 package, that job will execute, if I stuff all of them into a single package and pass through -Dspring.batch.job.names=job1,job2, it will execute both (or one if I want). But how can I get this command to work when the Application.java is at a different package scope? Is there a way to make it see those?

EDIT: So it looks like I can annotate my Application.java with

@Import({Job1BatchConfiguration.class, Job1JobCompletionNotificationListener.class, Job2BatchConfiguration.class, Job2JobCompletionNotificationListener.class})

But if I exceed more than even three jobs, this solution seems to get really sloppy. Any way to condense this functionality for the jobs?

My problem was solved putting my main class in package root of my struct.

Using the example showed, the location of Application is:

\---main
    +---java
    |   +---Application.java (Change location this file to package root)
    |   |       
    |   +---job1
    |   |       Job1BatchConfiguration.java
    |   |       Job1JobCompletionNotificationListener.java
    |   |       Job1Person.java
    |   |       Job1PersonItemProcessor.java
    |   |       
    |   \---job2
    |           Job2BatchConfiguration.java
    |           Job2JobCompletionNotificationListener.java
    |           Job2Person.java
    |           Job2PersonItemProcessor.java
    |           
    \---resources
            sample-data-2.csv
            sample-data.csv
            schema-all.sql

In your Application class add the annotation of @ComponentScan pointing at a higher package:

@ComponentScan("app")

or alternatively you can include multiple packages as well:

@ComponentScan("app.job1", "app.job2")

This annotation scans the packages and registers not only @Component or other beans but also @Configuration classes too.
