I want to add a custom build trigger to my build configurations (something similar to the maven build trigger which has been added to TeamCity 5.0, but it uses Ivy instead).
I guess I have to implement the jetbrains.buildServer.buildTriggers.BuildTrigger for this, but how can I extend the UI so that a new "build-trigger-tab" is displayed when configuring this ivy-build-trigger for my build configuration?
Sorry for delay, just found you question. The problem with BuildTrigger interface is that most likely it will be dropped after the TeamCity 5.0. If you want to implement custom trigger I would recommend to write a service which will trigger build manually and will be configured via property file.
We plan to improve triggers customization after the TeamCity 5.0 release.
