I am using the new Visual Studio build definitions on Visual Studio Online under Build. I would like to run a scheduled build every day for the branch TestingBuildDefinitions1 only if there have been changes in the branch since the previous build.
I cannot find the option to run scheduled builds only if there have been changes. The MSDN documentation says there should be a "Build even if nothing has changed since the previous build" checkbox. However, the new screen does not have this checkbox.
The documentation is referring to the old Xaml based builds, while the UI you are using is for the new VSO Build vNext, which does not have the functionality you are looking for. If you want to create a new Xaml based build, you will need to do it from the Visual Studio client (it cannot be done from the portal).
