Hello,
I’d like to know how to make GanttProject modify the duration (or end date) of a task depending on the (in)availability of a ressource allocated to the task.
Thank you
Effort-driven scheduling is not supported, sorry.

Thank you for the response.
Do you think it is a feature worth the implementation ?
Sure, but it is a non-trivial feature both from technical and UX perspectives.
There is an existing issue in the bug tracker:

In effort-driven scheduling a length of a task depends on the amount of
req… uired work (in man-days or man-hours) and availability of resources.
The basic rules is:
* If a task requires 3 man-days and a person who is doing this task is 50%
available then the task must become 6 days long.

OK, I understand. I’ll subscribe to the GitHub bugtracker thread to keep in touch.
Thanks
