A repo manifest describes the structure of a repo client; that is the directories that are visible and where they should be obtained from with git.
The basic structure of a manifest is a bare Git repository holding
a single default.xml
XML file in the top level directory.
Manifests are inherently version controlled, since they are kept
within a Git repository. Updates to manifests are automatically
obtained by clients during repo sync
.
[TOC]
A manifest XML file (e.g. default.xml
) roughly conforms to the
following DTD:
<!DOCTYPE manifest [
<!ELEMENT manifest (notice?,

For compatibility purposes across repo releases, all unknown elements are
silently ignored. However, repo reserves all possible names for itself for
future use. If you want to use custom elements, the x-*
namespace is
reserved for that purpose, and repo guarantees to never allocate any
corresponding names.
A description of the elements and their attributes follows.
The root element of the file.
Arbitrary text that is displayed to users whenever repo sync
finishes.
The content is simply passed through as it exists in the manifest.
One or more remote elements may be specified. Each remote element specifies a Git URL shared by one or more projects and (optionally) the Gerrit review server those projects upload changes through.
Attribute name
: A short name unique to this manifest file. The
name specified here is used as the remote name in each project's
.git/config, and is therefore automatically available to commands
like git fetch
, git remote
, git pull
and git push
.
Attribute alias
: The alias, if specified, is used to override
name
to be set as the remote name in each project's .git/config.
Its value can be duplicated while attribute name
has to be unique
in the manifest file. This helps each project to be able to have
same remote name which actually points to different remote url.
Attribute fetch
: The Git URL prefix for all projects which use
this remote. Each project's name is appended to this prefix to
form the actual URL used to clone the project.
Attribute pushurl
: The Git "push" URL prefix for all projects
which use this remote. Each project's name is appended to this
prefix to form the actual URL used to "git push" the project.
This attribute is optional; if not specified then "git push"
will use the same URL as the fetch
attribute.
Attribute review
: Hostname of the Gerrit server where reviews
are uploaded to by repo upload
. This attribute is optional;
if not specified then repo upload
will not function.
Attribute revision
: Name of a Git branch (e.g. main
or
refs/heads/main
). Remotes with their own revision will override
the default revision.
At most one default element may be specified. Its remote and revision attributes are used when a project element does not specify its own remote or revision attribute.
Attribute remote
: Name of a previously defined remote element.
Project elements lacking a remote attribute of their own will use
this remote.
Attribute revision
: Name of a Git branch (e.g. main
or
refs/heads/main
). Project elements lacking their own
revision attribute will use this revision.
Attribute dest-branch
: Name of a Git branch (e.g. main
).
Project elements not setting their own dest-branch
will inherit
this value. If this value is not set, projects will use revision
by default instead.
Attribute upstream
: Name of the Git ref in which a sha1
can be found. Used when syncing a revision locked manifest in
-c mode to avoid having to sync the entire ref space. Project elements
not setting their own upstream
will inherit this value.
Attribute sync-j
: Number of parallel jobs to use when synching.
Attribute sync-c
: Set to true to only sync the given Git
branch (specified in the revision
attribute) rather than the
whole ref space. Project elements lacking a sync-c element of
their own will use this value.
Attribute sync-s
: Set to true to also sync sub-projects.
Attribute sync-tags
: Set to false to only sync the given Git
branch (specified in the revision
attribute) rather than
the other ref tags.
At most one manifest-server may be specified. The url attribute is used to specify the URL of a manifest server, which is an XML RPC service.
The manifest server should implement the following RPC methods:
GetApprovedManifest(branch, target)
Return a manifest in which each project is pegged to a known good revision for the current branch and target. This is used by repo sync when the --smart-sync option is given.
The target to use is defined by environment variables TARGET_PRODUCT and TARGET_BUILD_VARIANT. These variables are used to create a string of the form $TARGET_PRODUCT-$TARGET_BUILD_VARIANT, e.g. passion-userdebug. If one of those variables or both are not present, the program will call GetApprovedManifest without the target parameter and the manifest server should choose a reasonable default target.
GetManifest(tag)
Return a manifest in which each project is pegged to the revision at the specified tag. This is used by repo sync when the --smart-tag option is given.
One or more submanifest elements may be specified. Each element describes a single manifest to be checked out as a child.
Attribute name
: A unique name (within the current (sub)manifest) for this
submanifest. It acts as a default for revision
below. The same name can be
used for submanifests with different parent (sub)manifests.
Attribute remote
: Name of a previously defined remote element.
If not supplied the remote given by the default element is used.
Attribute project
: The manifest project name. The project's name is appended
onto its remote's fetch URL to generate the actual URL to configure the Git
remote with. The URL gets formed as:
${remote_fetch}/${project_name}.git
where
The project name must match the name Gerrit knows, if Gerrit is being used for code reviews.
project
must not be empty, and may not be an absolute path or use "." or ".."
path components. It is always interpreted relative to the remote's fetch
settings, so if a different base path is needed, declare a different remote
with the new settings needed.
If not supplied the remote and project for this manifest will be used: remote
cannot be supplied.
Projects from a submanifest and its submanifests are added to the submanifest::path:<path_prefix> group.
Attribute manifest-name
: The manifest filename in the manifest project. If
not supplied, default.xml
is used.
Attribute revision
: Name of a Git branch (e.g. "main" or "refs/heads/main"),
tag (e.g. "refs/tags/stable"), or a commit hash. If not supplied, name
is
used.
Attribute path
: An optional path relative to the top directory
of the repo client where the submanifest repo client top directory
should be placed. If not supplied, revision
is used.
path
may not be an absolute path or use "." or ".." path components.
Attribute groups
: List of additional groups to which all projects
in the included submanifest belong. This appends and recurses, meaning
all projects in submanifests carry all parent submanifest groups.
Same syntax as the corresponding element of project
.
Attribute default-groups
: The list of manifest groups to sync if no
--groups=
parameter was specified at init. When that list is empty, use this
list instead of "default" as the list of groups to sync.
One or more project elements may be specified. Each element describes a single Git repository to be cloned into the repo client workspace. You may specify Git-submodules by creating a nested project. Git-submodules will be automatically recognized and inherit their parent's attributes, but those may be overridden by an explicitly specified project element.
Attribute name
: A unique name for this project. The project's
name is appended onto its remote's fetch URL to generate the actual
URL to configure the Git remote with. The URL gets formed as:
${remote_fetch}/${project_name}.git
where
The project name must match the name Gerrit knows, if Gerrit is being used for code reviews.
"name" must not be empty, and may not be an absolute path or use "." or ".." path components. It is always interpreted relative to the remote's fetch settings, so if a different base path is needed, declare a different remote with the new settings needed. These restrictions are not enforced for Local Manifests.
Attribute path
: An optional path relative to the top directory
of the repo client where the Git working directory for this project
should be placed. If not supplied the project "name" is used.
If the project has a parent element, its path will be prefixed
by the parent's.
"path" may not be an absolute path or use "." or ".." path components. These restrictions are not enforced for Local Manifests.
If you want to place files into the root of the checkout (e.g. a README or Makefile or another build script), use the copyfile or linkfile elements instead.
Attribute remote
: Name of a previously defined remote element.
If not supplied the remote given by the default element is used.
Attribute revision
: Name of the Git branch the manifest wants
to track for this project. Names can be relative to refs/heads
(e.g. just "main") or absolute (e.g. "refs/heads/main").
Tags and/or explicit SHA-1s should work in theory, but have not
been extensively tested. If not supplied the revision given by
the remote element is used if applicable, else the default
element is used.
Attribute dest-branch
: Name of a Git branch (e.g. main
).
When using repo upload
, changes will be submitted for code
review on this branch. If unspecified both here and in the
default element, revision
is used instead.
Attribute groups
: List of groups to which this project belongs,
whitespace or comma separated. All projects belong to the group
"all", and each project automatically belongs to a group of
its name:name
and path:path
. E.g. for
<project name="monkeys" path="barrel-of"/>
, that project
definition is implicitly in the following manifest groups:
default, name:monkeys, and path:barrel-of. If you place a project in the
group "notdefault", it will not be automatically downloaded by repo.
If the project has a parent element, the name
and path
here
are the prefixed ones.
Attribute sync-c
: Set to true to only sync the given Git
branch (specified in the revision
attribute) rather than the
whole ref space.
Attribute sync-s
: Set to true to also sync sub-projects.
Attribute upstream
: Name of the Git ref in which a sha1
can be found. Used when syncing a revision locked manifest in
-c mode to avoid having to sync the entire ref space.
Attribute clone-depth
: Set the depth to use when fetching this
project. If specified, this value will override any value given
to repo init with the --depth option on the command line.
Attribute force-path
: Set to true to force this project to create the
local mirror repository according to its path
attribute (if supplied)
rather than the name
attribute. This attribute only applies to the
local mirrors syncing, it will be ignored when syncing the projects in a
client working directory.
Modify the attributes of the named project.
This element is mostly useful in a local manifest file, to modify the attributes of an existing project without completely replacing the existing project definition. This makes the local manifest more robust against changes to the original manifest.
Attribute path
: If specified, limit the change to projects checked out
at the specified path, rather than all projects with the given name.
Attribute dest-path
: If specified, a path relative to the top directory
of the repo client where the Git working directory for this project
should be placed. This is used to move a project in the checkout by
overriding the existing path
setting.
Attribute groups
: List of additional groups to which this project
belongs. Same syntax as the corresponding element of project
.
Attribute revision
: If specified, overrides the revision of the original
project. Same syntax as the corresponding element of project
.
Attribute remote
: If specified, overrides the remote of the original
project. Same syntax as the corresponding element of project
.
Attribute dest-branch
: If specified, overrides the dest-branch of the original
project. Same syntax as the corresponding element of project
.
Attribute upstream
: If specified, overrides the upstream of the original
project. Same syntax as the corresponding element of project
.
Attribute base-rev
: If specified, adds a check against the revision
to be extended. Manifest parse will fail and give a list of mismatch extends
if the revisions being extended have changed since base-rev was set.
Intended for use with layered manifests using hash revisions to prevent
patch branches hiding newer upstream revisions. Also compares named refs
like branches or tags but is misleading if branches are used as base-rev.
Same syntax as the corresponding element of project
.
Zero or more annotation elements may be specified as children of a
project or remote element. Each element describes a name-value pair.
For projects, this name-value pair will be exported into each project's
environment during a 'forall' command, prefixed with REPO__
. In addition,
there is an optional attribute "keep" which accepts the case insensitive values
"true" (default) or "false". This attribute determines whether or not the
annotation will be kept when exported with the manifest subcommand.
Zero or more copyfile elements may be specified as children of a
project element. Each element describes a src-dest pair of files;
the "src" file will be copied to the "dest" place during repo sync
command.
"src" is project relative, "dest" is relative to the top of the tree. Copying from paths outside of the project or to paths outside of the repo client is not allowed.
"src" and "dest" must be files. Directories or symlinks are not allowed. Intermediate paths must not be symlinks either.
Parent directories of "dest" will be automatically created if missing.
It's just like copyfile and runs at the same time as copyfile but instead of copying it creates a symlink.
The symlink is created at "dest" (relative to the top of the tree) and points to the path specified by "src" which is a path in the project.
Parent directories of "dest" will be automatically created if missing.
The symlink target may be a file or directory, but it may not point outside of the repo client.
Deletes a project from the internal manifest table, possibly allowing a subsequent project element in the same manifest file to replace the project with a different source.
This element is mostly useful in a local manifest file, where the user can remove a project, and possibly replace it with their own definition.
The project name
or project path
can be used to specify the remove target
meaning one of them is required. If only name is specified, all
projects with that name are removed.
If both name and path are specified, only projects with the same name and path are removed, meaning projects with the same name but in other locations are kept.
If only path is specified, a matching project is removed regardless of its name. Logic otherwise behaves like both are specified.
Attribute optional
: Set to true to ignore remove-project elements with no
matching project
element.
Attribute base-rev
: If specified, adds a check against the revision
to be removed. Manifest parse will fail and give a list of mismatch removes
if the revisions being removed have changed since base-rev was set.
Intended for use with layered manifests using hash revisions to prevent
patch branches hiding newer upstream revisions. Also compares named refs
like branches or tags but is misleading if branches are used as base-rev.
Same syntax as the corresponding element of project
.
NB: See the practical documentation for using repo hooks.
Only one repo-hooks element may be specified at a time. Attempting to redefine it will fail to parse.
Attribute in-project
: The project where the hooks are defined. The value
must match the name
attribute (not the path
attribute) of a previously
defined project
element.
Attribute enabled-list
: List of hooks to use, whitespace or comma separated.
Note: This is currently a WIP.
NB: See the git superprojects documentation for background information.
This element is used to specify the URL of the superproject. It has "name" and "remote" as atrributes. Only "name" is required while the others have reasonable defaults. At most one superproject may be specified. Attempting to redefine it will fail to parse.
Attribute name
: A unique name for the superproject. This attribute has the
same meaning as project's name attribute. See the
element project for more information.
Attribute remote
: Name of a previously defined remote element.
If not supplied the remote given by the default element is used.
Attribute revision
: Name of the Git branch the manifest wants
to track for this superproject. If not supplied the revision given
by the remote element is used if applicable, else the default
element is used.
Note: This is currently a WIP.
This element is used to let manifest authors self-register contact info. It has "bugurl" as a required atrribute. This element can be repeated, and any later entries will clobber earlier ones. This would allow manifest authors who extend manifests to specify their own contact info.
Attribute bugurl
: The URL to file a bug against the manifest owner.
This element provides the capability of including another manifest file into the originating manifest. Normal rules apply for the target manifest to include - it must be a usable manifest on its own.
Attribute name
: the manifest to include, specified relative to
the manifest repository's root.
"name" may not be an absolute path or use "." or ".." path components. These restrictions are not enforced for Local Manifests.
Attribute groups
: List of additional groups to which all projects
in the included manifest belong. This appends and recurses, meaning
all projects in included manifests carry all parent include groups.
Same syntax as the corresponding element of project
.
Attribute revision
: Name of a Git branch (e.g. main
or refs/heads/main
)
default to which all projects in the included manifest belong.
Additional remotes and projects may be added through local manifest
files stored in $TOP_DIR/.repo/local_manifests/*.xml
.
For example:
$ ls .repo/local_manifests
local_manifest.xml
another_local_manifest.xml
$ cat .repo/local_manifests/local_manifest.xml
<?xml version="1.0" encoding="UTF-8"?>
<manifest>
<project path="manifest"
name="tools/manifest" />
<project path="platform-manifest"
name="platform/manifest" />
</manifest>
Users may add projects to the local manifest(s) prior to a repo sync
invocation, instructing repo to automatically download and manage
these extra projects.
Manifest files stored in $TOP_DIR/.repo/local_manifests/*.xml
will
be loaded in alphabetical order.
Projects from local manifest files are added into local:: group.
The legacy $TOP_DIR/.repo/local_manifest.xml
path is no longer supported.
