This is the fourth part (part 1, part 2, part 3) of a multi-part video series where Lincoln Baxter (@lincolnthree) and I are interactively building a Forge addon to add Java EE 7 Batch functionality.

Part 1 showed how to get started with creating an addon, add relevant POM dependencies, build and install the addon using Forge shell, add a new command batch-new-jobxml, and add --reader, --processor, --writer parameters to the newly added command.

Part 2 showed how to identify classes for each CLI parameter that already honor the contract required by the Batch specification.

Part 3 showed how parameters can be made required, created templates for reader, processor, and writer, validated the specified parameters.

This part shows:

• Fixed the issues from part 3 and generates new JobXML when reader, processor, and writer are specified
• Added a new test to test the command
• How Forge can be used in debug mode to debug add ons

Enjoy!

As always, the evolving source code is available at github.com/javaee-samples/forge-addons. The test code debugging will continue in the next episode.
