Build State

TeamCity considers a build as hanging when its run time significantly exceeds estimated average run time and the build did not send any messages since the estimation exceeded.

A running build can be marked as Outdated if there is a build which contains more changes but it is already finished.Hanging and outdated builds appear with the icon . Move the cursor over the icon to view a tooltip that displays additional information about the warning.

Builds which failed to start, that is which did not get to the point of launching the first build step are marked with the icon. It may be caused by a VCS repository being down when the build starts, or the inability to resolve artifact dependencies and so on. Such build status is often an indication of a configuration error and should usually be addressed by a build engineer rather than a developer.
If such an error occurs, TeamCity:

• doesn't send build failed notification (unless you have subscribed to "the build fails to start" notification)

• doesn't associate pending changes with this build, that is the changes will remain pending, because they were not actually tested

• doesn't show such build as the last finished build on the overview page

• such builds will not affect the build configuration status and the status of developer changes

• shows a "configuration error" stripe for a build configuration with such a build

A build's success or failure affects its color and the colors of its parent configuration and project. Color-coded icons provide a bird's eye view of the build farm, enabling you to instantly spot problematic projects.

TeamCity object icons have three distinctive colors:

Gray

• Build: not yet started (queued) or cancelled.

• Configuration: either the selected branch has no builds, or the default branch doesn't (for the side navigation tree and <All branches> view).

• Project: neither of the project configurations have builds.

Green

• Build: successfully finished or running without any issues.

• Configuration: the last build for a selected or default branch was successful.

• Project: all of its configurations are green.

Red

• Build: failed or still running but encountered a problem.

• Configuration: the last build for a selected or default branch failed.

• Project: at least one of its configurations is red.

The following images illustrate the same configuration with builds in three different branches: "main" (default branch), "development", and "sandbox".

• The last "development" branch build was successful. If this branch is selected, the configuration icon is green.

  

• The last "sandbox" branch build failed. If this branch is selected, the configuration icon is red.

  

• The default "main" branch has no builds, so configuration icons in both side navigation tree and <All branches> view are gray. The same "unknown" status applies to the entire project, since this is its only configuration.
