Script Runner examples

This code demonstrates getting a Gantt chart by structure id, initiating the resource leveling process for this Gantt chart, and then logging the progress until completion.

This example demonstrates how to programmatically manage a Gantt chart and its baselines. Initially, it checks for and deletes an existing Gantt chart for a given structure ID. Then, it creates a new Gantt chart and immediately finds it by name to ensure it's working with the correct chart. Before starting resource leveling, it creates a baseline for comparison purposes. The resource leveling process is then initiated for a specified resource, with enabled "Level resolved tasks" and "Level tasks in progress" options.
