Organizing Spring Batch Jobs

Question

I would like to add a Spring Batch module to Java 1.8, Maven 3.3.3 project for running batch jobs.

The module(s) should be a Maven child

of this parent:

<parent>
        <artifactId>portfolio-service-parent</artifactId>
        <groupId>com.distributedfinance</groupId>
        <version>1.0.0-SNAPSHOT</version>
    </parent>

At the moment I have three separate batch jobs. Is it better to organize all the batch jobs into one XML config file? Have three distinct modules each with it's own config file? One module with three distinct config files?

Thanks!

Here's the config file for the complex job:
