TeamCity supports Git out of the box. Git source control with Azure DevOps Services is supported (see authentication notes below ).
This page contains description of the Git-specific fields of the VCS root settings.
For common VCS root properties, see this section.
Initial Git checkout may take significant time (sometimes hours), depending on the size of your project history, because the whole project history is downloaded during the initial checkout.
The URL of the remote Git repository used for fetching data from the repository.
The URL of the target remote Git repository used for pushing annotated tags created via VCS labeling build feature to the remote repository. If blank, the fetch URL is used.
Configures default branch. Parameter references are supported here. Default value is
Lists the patterns for branch names, required for feature branches support. The matched branches are monitored for changes in addition to the default branch. The syntax is similar to checkout rules:
Use tags as branches
Allows monitoring / checking out git tags as branches making branch specification match tag names as well as branches (for example,
Defines a way TeamCity reports username for a VCS change. Changing the username style will affect only newly collected changes. Old changes will continue to be stored with the style that was active at the time of collecting changes.
Select whether you want to ignore the submodules, or treat them as a part of the source tree. Submodule repositories should either not require authentication or use the same protocol and accept the same authentication as configured in the VCS root.
Username for tags/merge
A custom username used for labeling.
Branch Matching Rules
If the branch matches a line without patterns, the line is used.
If the branch matches several lines with patterns, the best matching line is used.
If there are several lines with equal matching, the one below takes precedence.
Everything that is matched by the wildcard will be shown as a branch name in the TeamCity interface. For example,
refs/heads/feature1branch, but in the TeamCity interface you'll see only
feature1as a branch name.
The short name of the branch is determined as follows:
if the line contains no brackets, then full line is used, if there are no patterns or part of line starting with the first pattern-matched character to the last pattern-matched character.
if the line contains brackets, then part of the line within brackets is used. When branches are specified here, and if your build configuration has a VCS trigger and a change is found in some branch, TeamCity will trigger a build in this branch.
Supported Git Protocols
The following protocols are supported for Git repository URL:
ssh: (for example,
ssh://firstname.lastname@example.orgElse.org/repos/test.git, SCP-like syntax:
Select this option to clone a repository with anonymous read access.
Specify a valid username (if there is no username in the clone URL; the username specified here overrides the username from the URL) and a password to be used to clone the repository.
You can use a personal access token instead of a password to authenticate in GitHub, Azure DevOps Services, GitLab, and Bitbucket.
Valid only for SSH protocol. A private key must be in the OpenSSH format.
Select one of the options from the Private Key list and specify a valid username (if there is no username in the clone URL; the username specified here overrides the username from the URL).
For all available options to connect to GitHub, see the comment.
Authenticating to Azure DevOps Services
If you use Git source control with Azure DevOps Services, the following options are available to you:
Personal Access Tokens
To use access tokens, you need to create a personal access token in your Azure DevOps account, where you have to set some Code access scope in your repositories and use it when configuring a VCS root.
Leave blank for TFVC, any value for Git, for example, username
Enter your personal access token created earlier
Required Access Scope
Code (read) / Code (read and write) for versioned settings
Work items (read)
Alternate Authentication Credentials
To use the login/password pair authentication, you have to enable alternate credentials in your Azure DevOps account, where you can set a secondary username and password to use when configuring a VCS root.
These are the settings used in case of the server-side checkout.
Convert line-endings to CRLF
Convert line-endings of all text files to CRLF (works as setting
These are the settings used in case of the agent-side checkout.
Note that the agent-side checkout has limited support for SSH. The only supported authentication methods are "Default Private Key" and "Uploaded Private Key".
If you plan to use the agent-side checkout, you need to have Git 1.6.4+ installed on the agents.
Path to git
Provide the path to a Git executable to be used on the agent. When set to
Clean Policy/Clean Files Policy
Specify here when the
If a build configuration depends on multiple VCS roots, we suggest that you configure separate agent checkout directories for each of these roots, using VCS checkout rules. This way,
It is recommended to always leave this option enabled.
When enabled (default), TeamCity clones the Git repository and creates its mirror under the agent's
If you disable this option, TeamCity will clone the repository directly under the build's working directory.
Git executable on the agent
TeamCity needs Git command line client version 1.6.4+ on the agent in order to use the agent-side checkout.
The recommended approach is to ensure that the git client is available in
PATH of the TeamCity agent and leave the "Path to git" setting in the VCS root blank.
If you only have the git command line on some machines, set "Path to git" setting in the VCS root to the
Instead of adding Git to the agent's PATH, you can set the
TEAMCITY_GIT_PATH environment variable (or
env.TEAMCITY_GIT_PATH property in the agent's
buildAgent.properties file) to the full path to the git executable.
TEAMCITY_GIT_PATH is not defined, the Git agent plugin tries to detect the installed git on the launch of the agent. It first tries to run git from the following locations:
- for Windows — it tries to run
C:\Program Files (x86)\Git\bin
- for *nix — it tries to run
If Git is not found in any of these locations, it tries to run the git accessible via the
PATH environment variable.
If a compatible git (1.6.4+) is found, it is reported in the
TEAMCITY_GIT_PATH environment variable. This variable can be used in the Path to git field in the VCS root settings. As a result, the configuration with such a VCS root will run only on the agents where Git was detected or specified in the agent properties.
TeamCity supports Git LFS for agent-side checkout. To use it, install git 1.8.+ and Git LFS on the build agent machine. Git LFS should be enabled using the
git lfs install command (on Windows, an elevated command prompt may be needed). More information is available in the Git LFS documentation.
For LFS, you need to use the same credentials as used for the Git VCS root itself.
We recommend using Git LFS version 2.12.1 or later as earlier versions come with a vulnerability.
The Git plugin uses
git sparce-checkout to check out Git files on an agent. The plugin is able to perform only simple file mapping operations which limits the set of supported VCS checkout rules for Git.
The following rules are supported:
If you specify multiple checkout rules for one root, make sure their checkout directories (the right part of the rule) have a common parent directory. For example:
Git support is implemented as an open-source plugin. For development links, refer to the plugin's page.
