That particular page is a knowledge base article rather than regular support documentation, so there doesn't appear to be a more updated version of it. However, it does reference articles in our Development documentation that are updated, such as Building Jira from Source.
I would recommend reading through the documentation there, and let us know if you have any trouble on the more recent version of Jira.
Not sure if you are following the latest posts related to building source, there are few unresolved issues causing us unable to build the 7.5 source. I have posted below questions last week but they are not answered. I have also posted the questions on developer community but no luck. Could you please take a look at the below issues related to building JIRA source and suggest?
I am not familiar with that, thank you for bringing that to my attention.
The developer forum that you said that you went to is really the best place for help with this , since most Jira users won't be building patches and applying them, so hopefully you will receive an update there soon.
I don't have any information on the first link you posted but if you posted the same in the developer forum then I would expect an answer for you there. I see my colleague Andrew has been helping you on the other case.
