Countersoft Gemini Support

I know there are some posts already asking for the same but they're all old and I'm really not sure if anything applies anymore, specially the links to the plugins documentations, the feature seems to have either changed or disappeared at some point.

As developers push their fixes to Teamcity the build automatically publishes binaries to our pre-production environments and QA team. At this point the developers have to manually update the tickets in Gemini to make them Ready for QA. What I'm trying to achieve with this post is a way to configure TeamCity to automatically update the resolution of the tickets once a certain condition is met. I have two ideas from the top of my head but perhaps any of you guys could point me in a better direction or explain how to achieve any of these:

1. Once the developer completes a tickets and pushes the last commit he updates the ticket as Pending Build (or something similar) and, after the build is completed, TeamCity updates all the tickets within Gemini that are included in the build (based on the VCS changes) and that are marked as Pending Build to Ready for QA.
2. Another option would be to include a special tag in the commit message such as [rfqa] or something and then TeamCity updates the tickets for those commits.

Note that developers are required to include a special tag in each commit to link them to Gemini already, so I have ways to determine what is the ticket number based on the commit message. Also note that I'm not a java developer so creating a jar plugin would be rather inconvenient.
