Jira Plugins Development Integration Plugin - 5.5.3

Where I can find documentation for Atlassian Jira - Plugins - Development Integration Plugin - 5.5.3 ?

Found this post.


but links are dead. Please advise.

https://jira.atlassian.com/browse/JSWSERVER-15321
There is no published javadoc. The source code is under dependencySources in the source code download from Atlassian. Probably your best bet.

Besides non public API, any way I can retrieve information from the Development Board?
Such as git commit/push from Github through DVCS

example as below
