Minyaa - Auto-Transition Management

Basically, in JIRA, is considered as Auto-Transition, any Workfow Transition where its Initiator is not directly raised by the user through the UI.

In JIRA Community, there are different ways to implement an Auto-Transition, where different definitions of Auto-Transition coexist.

You will see Auto Transition done

using a Jelly Script executed by the Jelly Script Runner Service (Atlassian Jelly Escalation)
using a Post-function, able to evaluate a Groovy Script (See different Built-in Script for Groovy Script Runner, Blog Post)
using a Event Listener able to transition an action by its Id on an issue event (Auto Transition Listener of JIRA Toolkit Plugin)
using a Post-function, able to transition an action by its Id. (Implemented by Transition All Substasks Plugin)

See Minyaa's Blog Post ...

To implement Auto-Transitions, you have to identify

Which transitions have to be executed ?
- Any available Auto-Transition identified in linked Issue (sub-Task or any Linked Issues) of the current Issue
- Any available Auto-Transition identified in any Issue
- A Transition identified by its Id. in linked Issue (sub-Task or any Linked Issues)
When they have to be executed ? An Auto-Transition can be raised by different events :
- Internal Transition : the transition is launched automatically after another transition of the same issue
- External Transition : the transition is launched automatically after a transition of the another issue
- Change Event : the transition is launched automatically depending on an any event related to change in the context of the issue (any Field value, Actor, Project, Version, ...)
- Temporal Event : the transition is launched automatically depending on an temporal event

Depending on these criteria, we are able to implement different types of Auto-Transition.

And then, you will be able to decide How to implement your Auto-Transition.

To cover these features, Minyaa provides different mechanisms ...

Auto-Transition Manager : It is in charge of transitioning candidate Auto-Transitions
Auto-Transition Properties : They allows to qualify an Auto-Transition and to alter a part of the transition's behavior.
Auto-Transition Service : It is used to check periodically some issues.
Auto-Transition Post-Functions : They allows to init some Auto-Transitions

Some Use Cases where Auto-Transition may be encountered :

Use Case	Description	Implementation
Auto-Triage	A priority is applied depending different fields	Automatic Actions
Auto-Assignment	A user is assigned depending different fields (other than Component)	Automatic Actions
Need more Information	As soon as a new comment is added by the reporter/customer, the issue has to passed to the next step	Auto-Transition initiated from a Listener
Inactivity	No activity on the issue (Comment, Transition, Worklog, Edit) since a specified delay	Auto-Transition initiated from a Auto-Transition Service
Auto-Close of linked Issue	On Issue Close, we want see linked Issue, also closed.	Remote-Transition initiated from a Auto-Transition Post-Function
...	...	...

You should be able to find the good implementation to resolve your own Use Case ...
