We start our demo app as usual using the already provided launch scripts but once it starts we do not launch our browser and go to localhost:8090 (default) to access it, but instead we are presented with a prompt and can start typing in our commands to interact with our business processes.

• deploy <groupId> <artifactId> <version>
• processdefs
• processinstances
• startprocess <processDefId> <deploymentId>

Our deploy command allows us to deploy a kjar module which is available in our local maven repository. The demo app comes with one such module which you can use to deploy after the application has started with the command:

The processdefs command simply shows all currently available process definition (across all deployments):

The startprocess command allows you to start a business process. It takes in the process definition id and the deployment unit id (if deployment unit id is not specified, the default one is assumed). So for example to start our “firstTestProcess” business process we can do:

Lastly, the processinstances command shows all process instances that are available, for example:
