TeamCity uses the typical Mercurial command line client: hg command. Mercurial 1.5.2+ is supported.

Icon

Mercurial is to be installed on the server machine and, if the agent-side checkout is used, on the agents.

Note that:

  • Remote Run from IDE is not supported. Please use Branch Remote Run Trigger instead.
  • Checkout rules for agent-side checkout are not supported except for the .=><target_dir> rule.

Common VCS Root properties are described here. The section below contains the description of Mercurial-specific fields and options.

Mercurial support in TeamCity is implemented as a plugin.

On this page:

General Settings

Option

Description

Pull changes from

The URL of your hosting.

Default branch

Set to the default branch which used in the absence of branch specification or when the branch of the branch specification cannot be found. Note that parameter references are supported here.

Branch specification

In this area list all the branches you want to be monitored for changes. The syntax is similar to checkout rules: +|-:branch_name, where branch_name is specific to the VCS (with the optional * placeholder). Note that only one asterisk is allowed and each rule has to start with a new line.
Bookmarks can also be used in the branch and branch specification fields. If a bookmark has the same name as a regular branch, a regular branch wins. More in the related TeamCity blogpost.

Icon

Bookmarks support requires Mercurial 2.4 installed on the TeamCity server.

Use tags as branches

Allows you to use tags in branch specification. By default, tags are ignored.

Detect subrepo changes

By default, subrepositories are not monitored for changes.

Username for tags/merge

A custom username used for labeling

Use uncompressed transfer

Uncompressed transfer is faster for repositories in the LAN.

HG command path

The path to the hg executable. See more below.

Mercurial config

Specify the Mercurial configuration options to be applied to the repository, e.g. enter the following to enable the largefiles extension:
[extensions]
largefiles =
The configuration format is described here.

Path to hg executable detection

When an agent starts, the hg-plugin detects Mercurial installed on the agent machine.

The plugin tries to run the hg version command using the path specified by teamcity.hg.agent.path parameter. You can change this parameter in <Agent Home Directory>\conf\buildAgent.properties.

If this parameter is not set, the plugin uses hg as a path to the command, assuming it is somewhere in the $PATH. If the command is executed successfully and mercurial has an appropriate version (1.5.2+), then the hg-plugin reports the path to hg in the teamcity.hg.agent.path parameter.

During the build, the plugin uses the hg specified in the HG command path field of a VCS root settings. To use the detected hg, put %teamcity.hg.agent.path% in this field. Configurations with such settings will be run only on agents which report the path to hg.

The server side of the plugin first checks the value of the teamcity.hg.server.path internal property and if the property is set, its value is used. Secondly, the plugin tries to use the path from the settings of VCS root: if the path is equal to %teamcity.hg.agent.path%, it uses hg as a path, otherwise uses the value specified in the root settings.

Agent Settings

These are the settings used in case of the agent-side checkout (default mode since TeamCity 10.0), which requires Mercurial installed on all agents.

Option

Description

Purge settings

Defines whether to purge files and directories not being tracked by Mercurial in the current repository. You can choose to remove only unknown files and empty directories, or to remove ignored files as well. Added files and (unmodified or modified) tracked files are preserved.

Use mirrors

When enabled, TeamCity creates a local agent mirror first (under agent's system/mercurial directory) and then clones to the working directory from this local mirror. This option speeds up clean checkout, because only the build working directory is cleaned. Also, if a single root is used in several build configurations, a clone will be faster.

Internal Properties

This section describes hg-related internal properties. You can modify the defaults to adjust the Mercurial settings as needed.

Server-side internal properties:

teamcity.hg.pull.timeout.seconds

Maximum time in seconds for pull operation to run

teamcity.hg.server.path

hg

Path to the hg executable on the server (see Path to hg executable detection for the details).

Agent configuration for Mercurial:
