Source code for Atlassian Roadmap (Jira ver 7.12.3)

[Alexander]

Hi, can I obtain the source code for Atlassian Roadmap? For Jira Server ver 7.12.3?
What is required for that?
At my.atlassian.com there'no such option,
it's impossible to choose Atlassian Roadmap and purchase it for this Jira version (7.12.3).

Atlassian do not publish the code for most of their apps, Advanced Roadmaps being one of them.

New sales of Server Apps that are being rolled into the Data Center applications ended on the 2nd February 2021, which is why you can't find, install or buy it. See https://www.atlassian.com/migration/journey-to-cloud

If you want Advanced Roadmaps, you'll need to move to Data Center or Cloud (premium) to get it now.
