Jira API - which Java class contains the constants for Status and Transitions?

[Ramkumar Krishnan]

This is a follow-up to this Solved thread: https://community.atlassian.com/t5/Jira-Service-Management/How-to-change-the-status-of-a-Jira-ticket-from-OPEN-to-Under/qaq-p/1514306

Which com.atlassian.jira class contains the constant declarations for Status values and Transition values?

To clarify, I want to avoid declaring local variables like this:

public final String RESOLVE_TRANSITION = "Resolved";
private static final int RESOLVE_TRANSITION_ID = 201;

but instead use the named constants provided from the Jira API class (to insulate myself from any future changes or deprecation). The question is: what class should I import in my Java code to get these constants?

Thanks

Welcome to the Atlassian Community!

The short answer is that "you don't". 

Workflows are variable.  As soon as anyone edits a workflow (and one of Jira's greatest powers is that you can), you have a change that you can't guess reliably that has moved away from the defaults.

There are no things like "RESOLVE_TRANSITION" or "RESOLVE_TRANSITION_ID", and even if they were, I can absolutely guarantee you that you have different values for them in your system, let alone looking wider.

There are no constants for status or transitions.
