Exporting an app programmatically can be done by invoking the function appService.exportApp() manually in the beanshell script. We will be using a BeanShell tool inside a process that we can trigger as needed.
Steps Example
1: Create Process
Create a new process in the process builder and build it in such a way as seen in Figure 1. Paste the provided script into the tool.
Figure 1: The process
2: Create UI element
Drag a Run Process UI element in the UI Builder and have it point to the process created in Step 1.
Figure 2: Run Process Element that points to Process 1
Script
** Do note that the variable "path" in the code is contextual to your preference/environment and needs to be changed to suit your requirements.
** You will also need to either/or
- provide sufficient permission level to Tomcat (or your Java container used to run Joget)
- create a location/folder that allows Tomcat to read/write files

Result
For this example, all app files will be saved into /wflow/jwa_backup folder
