TeamCity can label (tag) sources of a particular build (automatically or manually) in your Version Control System. The list of applied labels and their application status is displayed on the Changes tab of the Build Results page.
Automatic VCS labeling
You can set TeamCity to label the sources of a build depending on the build status automatically. The process takes place in the background after the build finishes and does not affect the build status, which means that a labeling failure is not a standard notification event. However, the users subscribed to notifications about failed builds of the current build configuration will be notified about a labeling failure.
Any errors encountered during labeling are reported on the Changes tab of the Build Results page.
Labeling is configured per a build configuration/template.
Automatic VCS labeling is configured as a build feature. When adding the feature, you will need to specify the root to label and the labeling pattern.
If there are branches configured for a build configuration, you can label only builds from specific branches you select.
It is possible to override the labeling settings inherited from a template completely and apply different labels to different VCS roots.
Note that if you change the VCS settings of a build configuration, they will be used for labeling only in the new builds.
"Moving" labels (a label with the same name for different builds, for example,
SNAPSHOT) are currently supported only for CVS.
For an example of using the Teamcity VCS labeling feature to automate tag creation, refer to this external posting.
Manual VCS labeling
To label the sources manually, navigate to the Build Results page, click Actions, and select Label this build sources from the drop-down menu.
Manual labeling uses the VCS settings actual for the build.
Subversion Labeling Rules
To label Subversion VCS roots, it is required to set labeling rules defining the SVN repository structure.
Labeling rules are specified as newline-delimited rules in the following format:
The repository paths can be relative and absolute (starting with
/). Absolute paths are resolved from the SVN repository root (the topmost directory you have in your repository), relative paths are resolved from the TeamCity VCS root.
When creating a label, the sources residing under
TrunkOrBranchRepositoryPath will be put into the
tagDirectoryRepositoryPath/tagName directory, where
tagName is the name of the label as defined by the labeling pattern of the build configuration.
If no sources match the
TrunkOrBranchRepositoryPath, no label will be created.
tagDirectoryRepositoryPath path must already exist in the repository.
tagDirectoryRepositoryPath directory already contains a subdirectory with the current label name, the labeling process will fail, and the old tag directory won't be deleted or affected.
For example, there is a VCS root with the URL
svn://address/root is the repository root, and the repository has the structure:
In this case, the labeling rules should be:
Labeling Rule Examples
You can use variables substitution in both labeling rules and labeling patterns. See a labeling rule example in a VCS root used in different configurations:
This will require you to set the
%projectName% configuration parameter in the build configuration settings.
By default, TeamCity will append the label name to the end of the specified target path. If you want to have a different directory structure and put the label in the middle of the target path, you can use the following syntax:
%%system.build.label%% will be replaced with the tag name (note the double
%% sign at the beginning – it is important).
