TeamCity Cloud 2023.11 Help


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.

Important notes:

Native Git for VCS-related operations on the server

TeamCity can now use native Git for VCS-related operations on the server. Using native Git improves the performance of the checking for changes operations on the server in comparison with the previously used JGit implementation. It also fixes a number of issues related to large Git repositories.

See known issues of the current native Git implementation in TeamCity.

General Settings



Fetch URL

The URL of the remote Git repository used for fetching data from the repository.

Push URL

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.

Default branch

Configures default branch. Parameter references are supported here. Default value is refs/heads/master.

Branch specification

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: +|-:branch_name, where branch_name is specific to the VCS, i.e. refs/heads/ in Git (with the optional * placeholder).

Use tags as branches

Allows monitoring / checking out git tags as branches making branch specification match tag names as well as branches (for example,+|-:refs/tags/<tag_name>). By default, tags are ignored.

Username style

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/* will match refs/heads/feature1 branch, but in the TeamCity interface you'll see only feature1 as 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://, ssh://, SCP-like syntax:

Authentication Settings

Authentication Method



Select this option to clone a repository with anonymous read access.

Password / personal access token

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.
For the agent-side checkout, it is supported only if Git 1.7.3+ client is installed on the agent. See TW-18711.
For Git hosted from Team Foundation Server 2013, specify NTLM credentials here.

You can use a personal access token instead of a password to authenticate in GitHub, Azure DevOps Services, GitLab, JetBrains Space, and Bitbucket. When connecting to Azure DevOps, remember to set the Code access scope to Code (read) / Code (read and write) for versioned settings in the repositories you are about to access from TeamCity.

When using an existing Bitbucket Cloud, Bitbucket Server, GitLab or Azure DevOps Services connection to create a VCS Root, TeamCity will use a refreshable token instead of the password.

Refreshable token

If a VCS root that fetches data from a GitHub, GitHub App, Bitbucket Server, Bitbucket Cloud, Azure DevOps, GitLab, or JetBrains Space was configured using a TeamCity connection, refreshable tokens are enabled by default. Such tokens are short-lived providing more security than passwords or personal access tokens: the TeamCity server refreshes them automatically without sharing any related data with agents.

The Token field displays information about the user who obtained the token and the connection that provided the token.

You can specify a username here if there is no username in the clone URL (the username specified here overrides the username from the URL).

For Azure DevOps, GitHub App, Bitbucket Server, Bitbucket Cloud, JetBrains Space and GitLab connections you can click the Acquire new button to instantly reissue the token used by the VCS root with a token issued for the current user.

Reissue Token

Private Key

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).
Available Private Key options:

  • Uploaded Key — select this option to utilize the key(s) uploaded to the project.

  • Default Private Key — select this option to utilize the keys available on the file system in the default locations used by common ssh tools: the mapping specified in <USER_HOME>/.ssh/config if the file exists or the private key file <USER_HOME>/.ssh/id_rsa (the files are required to be present on the server and also on the agent if the agent-side checkout is used).

  • Custom Private Key — supported only for server-side checkout. Fill the Private Key Path field with an absolute path to the private key file on the server machine. If the key is encrypted, specify the passphrase in the corresponding field.

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, you can use both Azure DevOps OAuth and Azure DevOps PAT connections.

Server Settings

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 core.autocrlf=true in a repository config). When not selected, no line-endings conversion is performed (works as setting core.autocrlf=false). Affects the server-side checkout only. A change to this property causes a clean checkout.

Agent Settings

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 %env.TEAMCITY_GIT_PATH%, the automatically detected Git will be used, see Git executable on the agent for details.

Checkout policy

This setting defines how TeamCity performs a checkout to a build agent.

  • Use mirrors: recommended for long-lived agents. With this option selected, TeamCity creates a remote repository cache on the agent machine under the system/caches/git directory. The cache is then added as alternates when updating the build checkout directory. To speed up the following checkouts of this repository, the agent will reuse the cache in all the builds with the same fetch URL. This also speeds up clean checkout (as only the build working directory is cleaned) and saves disk space (as the mirror is the only clone of the given repository on the agent).

  • Do not use mirrors: choose to check out right into the build checkout directory, without creating a mirror. Less optimal in terms of disk usage than mirrors, but preserved for backwards compatibility with existing configurations.

  • Shallow clone: recommended for short-lived agents; for example, for disposable cloud agents being terminated after every build. Creates a shallow clone by fetching only one required revision, which allows saving time on the build start. Choose this option only if you do not require a Git commit history in your builds and if your cloud image does not contain a fresh Git mirror. You can enforce this option on certain agents by specifying the teamcity.git.shallowClone=true agent configuration property.

  • Auto: TeamCity will automatically apply one of the above approaches depending on the agent configuration property and on the mirror presence on the agent.

Clean Policy/Clean Files Policy

Specify here when the git clean command is to run on the agent, and which files are to be removed.

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, git clean will never delete these checkout directories during cleaning.

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 %env.TEAMCITY_GIT_PATH% value.

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 file) to the full path to the git executable.

If 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 git.exe at:

    • C:\Program Files\Git\bin

    • C:\Program Files (x86)\Git\bin

    • C:\cygwin\bin

  • for *nix — it tries to run git at:

    • /usr/local/bin

    • /usr/bin

    • /opt/local/bin

    • /opt/bin

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 exploit.

Agent-side checkout rules limitations

The Git plugin uses git sparse-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:

+:dirA/dirA1 -:dirA/dirA1/dirA2 +:. => dirA/dirA1/dirA2 +:dirA => dirA +:dirA/dirA1 => dirA/dirA1 +:dirA/dirB/dirC => dirD/dirE/dirA/dirB/dirC

Note that rules must not remap files. That is, the following rule is not supported: +:dirA/dirA1 => dirA/dirA2.

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 ([prefix/]). Only the rules +:dirA => [prefix/]dirA are supported for agent-side checkout, and the [prefix/] must be the same for all rules.

For example:

+:dirA/dirB/dirC => [prefix/]dirA/dirB/dirC +:dirD/dirE/dirF => [prefix/]dirD/dirE/dirF

Note that the following rule is not supported: +:dirA=>[prefix/]dirA/postfix. If you append [/postfix] to the checkout directory path and the configuration's VCS checkout mode is set to "Always checkout files on agent", new builds will be unable to start.
