I have an open source project that I’d like to fork and then maintain a package for. The upstream project uses gobuilder, which creates a bunch of package formats and then publishes to github. I’d like these to be available in OBS instead. Has anyone successfully integrated gobuilder with the build service in some way that interrupts the process stopping at “spec and source are generated”? I’m having a hard time finding how to do that, or if it’s (reasonably) possible. Then again, I’m also really weak with Golang itself and even weaker with the associated ecosystem, so that’s not saying much. 
You might want to reconsider your build options.
Looks like the GoBuilder project is dead…
Last update was many years ago, and the Domain used by GoBuilder (gobuilder.me) is not active and for sale.
