There seems to be a plethora of apps in the Atlassian Marketplace for connecting Jira to Development tools - GitHub, GitLab, Bitbucket, Jenkins, etc.
Despite so many, there also seems to be just a handful of actual development tools being connected.
That being the case, what are the challenges you have found in connecting the tools to Jira and what has worked best for you? Do you have this documented? Have you done any videos showing the process?
I am not looking for vendor marketing responses and material. I am looking for actual users who have implemented (or attempted to implement) the connections and what went well, what are the pitfalls, what should you just plain avoid?
