Access to confluence-jira-plugin code on bitbucket.org

This post from a while back has a link to confluence-jira-plugin source that I’m looking for:

But when I go to Log in with Atlassian account, I get:

We can’t let you see this page

I’m logged in. Why can’t I see it?

Hei hei
I see that the repo is private which explains why you do not have access to it.
Anything in particular around macros/confluence/jira that I can help with ?

I am trying to add Jira search and/or create on a page blueprint create wizard. So, for example, page 1 asks some questions via lists/text/etc. On page 2, I would like users to be able to search for an Issue or create a new one as if they are using the jiraissue macro.

I was planning to look at the code to see how it can be done.

Can it be done with javascript?
