TeamCity triggers too many builds for a new branch

Question

When I create a new branch B from branch A and do a single commit, TeamCity triggers multiple builds on B, although I would expect just a single build.
I set "Trigger a build on each check-in" to true, but nevertheless there should only be a single build because there is only one new commit. It seems that TeamCity triggers a build for each commit within the current month. All builds of branch A finished and the same build configuration is used to build branch A and B. Can I configure TeamCity to create builds just for the commits that haven't been built (no matter on which branch)?

I've had this happen before, but I'm not sure what the reason was. In this case I cancel all the outstanding builds and then rerun the build, which always seems to batch the changes altogether in one build. – Rivalee

Of course this would work, but it's obviously not a sustainable solution. Can you remember if you changed anything or did it just disappear or did you reinstall the whole system? – Castorena

Answer 1

It looks like you faced with this issue. As current workaround please try to set

teamcity.vcsTrigger.runBuildOnSameRevisionInEveryBranch=false

You can set it either as a parameter in build configuration - to affect a particular build configuration, or in internal.properties file to affect all build configurations.

Thanks, that seems to do the job, although it still triggers a build when a new branch without changes is created. But I guess one build won't hurt. – Castorena

Where to set this? Exactly? Why can't there be some kind of interface with checkboxes for those boolean values. – Shivery

Answer 2

I suppose you have activated the VCS build trigger for that Build Configuration. So, go to that Build Configuration settings page > Triggers > and look for the VCS trigger. Click the edit link and a modal will appear, there will be the option you are looking for: "Trigger a build on each check in": https://confluence.jetbrains.com/display/TCD8/Configuring+VCS+Triggers#ConfiguringVCSTriggers-PercheckinTriggering

Thanks. Although I want it to trigger on each check-in. But imagine I work on a feature branch which gets continuously built by TeamCity. When I then merge it back to the main branch I don't want a build triggered for each commit as they already have been triggered on the other branch. – Castorena

So runBuildOnSameRevisionInEveryBranch seems exactly what i wanted. – Castorena
