archive_override
None
archive_override(module_name, urls, integrity='', strip_prefix='', patches=[], patch_cmds=[], patch_strip=0)
Specifies that this dependency should come from an archive file (zip, gzip, etc) at a certain location, instead of from a registry. This directive only takes effect in the root module; in other words, if a module is used as a dependency by others, its own overrides are ignored.

version
|
default is '' The version of the module to be added as a direct dependency. |
max_compatibility_level

git_override
None
git_override(module_name, remote, commit='', patches=[], patch_cmds=[], patch_strip=0, init_submodules=False)
Specifies that a dependency should come from a certain commit of a Git repository. This directive only takes effect in the root module; in other words, if a module is used as a dependency by others, its own overrides are ignored.
Parameters
Parameter | Description |
---|---|
module_name
|
required The name of the Bazel module dependency to apply this override to. |
remote
|
required The URL of the remote Git repository. |
commit
|
default is '' The commit that should be checked out. |
patches
|
Iterable of strings;
default is [] A list of labels pointing to patch files to apply for this module. The patch files must exist in the source tree of the top level project. They are applied in the list order. |
patch_cmds
|
Iterable of strings;

local_path_override
None
local_path_override(module_name, path)
Specifies that a dependency should come from a certain directory on local disk. This directive only takes effect in the root module; in other words, if a module is used as a dependency by others, its own overrides are ignored.
Parameters
Parameter | Description |
---|---|
module_name
|
required The name of the Bazel module dependency to apply this override to. |
path
|
required The path to the directory where this module is. |
module
None
module(name='', version='', compatibility_level=0, repo_name='', bazel_compatibility=[])
Declares certain properties of the Bazel module represented by the current Bazel repo. These properties are either essential metadata of the module (such as the name and version), or affect behavior of the current module and its dependents. It should be called at most once. It can be omitted only if this module is the root module (as in, if it's not going to be depended on by another module).
Parameters
Parameter | Description |
---|---|
name
|
default is '' The name of the module. Can be omitted only if this module is the root module (as in, if it's not going to be depended on by another module). A valid module name must: 1) only contain lowercase letters (a-z), digits (0-9), dots (.), hyphens (-), and underscores (_); 2) begin with a lowercase letter; 3) end with a lowercase letter or digit. |
version
|
default is '' The version of the module. Can be omitted only if this module is the root module (as in, if it's not going to be depended on by another module). The version must be in a relaxed SemVer format; see the documentation for more details. |
compatibility_level
|
default is 0 The compatibility level of the module; this should be changed every time a major incompatible change is introduced. This is essentially the "major version" of the module in terms of SemVer, except that it's not embedded in the version string itself, but exists as a separate field. Modules with different compatibility levels participate in version resolution as if they're modules with different names, but the final dependency graph cannot contain multiple modules with the same name but different compatibility levels (unless multiple_version_override is in effect). See the documentation for more details.
|
repo_name
|
default is '' The name of the repository representing this module, as seen by the module itself. By default, the name of the repo is the name of the module. This can be specified to ease migration for projects that have been using a repo name for itself that differs from its module name. |
bazel_compatibility
|
Iterable of strings;
default is [] A list of bazel versions that allows users to declare which Bazel versions are compatible with this module. It does NOT affect dependency resolution, but bzlmod will use this information to check if your current Bazel version is compatible. The format of this value is a string of some constraint values separated by comma. Three constraints are supported: <=X.X.X: The Bazel version must be equal or older than X.X.X. Used when there is a known incompatible change in a newer version. >=X.X.X: The Bazel version must be equal or newer than X.X.X.Used when you depend on some features that are only available since X.X.X. -X.X.X: The Bazel version X.X.X is not compatible. Used when there is a bug in X.X.X that breaks you, but fixed in later versions. |
multiple_version_override
None
multiple_version_override(module_name, versions, registry='')
Specifies that a dependency should still come from a registry, but multiple versions of it should be allowed to coexist. See the documentation for more details. This directive only takes effect in the root module; in other words, if a module is used as a dependency by others, its own overrides are ignored.
Parameters
Parameter | Description |
---|---|
module_name
|
required The name of the Bazel module dependency to apply this override to. |
versions
|
Iterable of strings;
required Explicitly specifies the versions allowed to coexist. These versions must already be present in the dependency graph pre-selection. Dependencies on this module will be "upgraded" to the nearest higher allowed version at the same compatibility level, whereas dependencies that have a higher version than any allowed versions at the same compatibility level will cause an error. |
registry
|
default is '' Overrides the registry for this module; instead of finding this module from the default list of registries, the given registry should be used. |
register_execution_platforms
None
register_execution_platforms(dev_dependency=False, *platform_labels)
Specifies already-defined execution platforms to be registered when this module is selected. Should be absolute target patterns (ie. beginning with either @
or //
). See toolchain resolution for more information.
Parameters
Parameter | Description |
---|---|
dev_dependency
|
default is False If true, the execution platforms will not be registered if the current module is not the root module or `--ignore_dev_dependency` is enabled. |
platform_labels
|
sequence of strings;
required The labels of the platforms to register. |
register_toolchains
None
register_toolchains(dev_dependency=False, *toolchain_labels)
Specifies already-defined toolchains to be registered when this module is selected. Should be absolute target patterns (ie. beginning with either @
or //
). See toolchain resolution for more information.
Parameters
Parameter | Description |
---|---|
dev_dependency
|
default is False If true, the toolchains will not be registered if the current module is not the root module or `--ignore_dev_dependency` is enabled. |
toolchain_labels
|
sequence of strings;
required The labels of the toolchains to register. Labels can include :all , in which case, all toolchain-providing targets in the package will be registered in lexicographical order by name.
|
single_version_override
None
single_version_override(module_name, version='', registry='', patches=[], patch_cmds=[], patch_strip=0)
Specifies that a dependency should still come from a registry, but its version should be pinned, or its registry overridden, or a list of patches applied. This directive only takes effect in the root module; in other words, if a module is used as a dependency by others, its own overrides are ignored.
Parameters
Parameter | Description |
---|---|
module_name
|
required The name of the Bazel module dependency to apply this override to. |
version
|
default is '' Overrides the declared version of this module in the dependency graph. In other words, this module will be "pinned" to this override version. This attribute can be omitted if all one wants to override is the registry or the patches. |
registry
|
default is '' Overrides the registry for this module; instead of finding this module from the default list of registries, the given registry should be used. |
patches
|
Iterable of strings;
default is [] A list of labels pointing to patch files to apply for this module. The patch files must exist in the source tree of the top level project. They are applied in the list order. |
patch_cmds
|
Iterable of strings;
default is [] Sequence of Bash commands to be applied on Linux/Macos after patches are applied. |
patch_strip
|
default is 0 Same as the --strip argument of Unix patch. |
use_extension
module_extension_proxy use_extension(extension_bzl_file, extension_name, *, dev_dependency=False, isolate=False)Returns a proxy object representing a module extension; its methods can be invoked to create module extension tags.
Parameters
Parameter | Description |
---|---|
extension_bzl_file
|
required A label to the Starlark file defining the module extension. |
extension_name
|
required The name of the module extension to use. A symbol with this name must be exported by the Starlark file. |
dev_dependency
|
default is False If true, this usage of the module extension will be ignored if the current module is not the root module or `--ignore_dev_dependency` is enabled. |
isolate
|
default is False Experimental. This parameter is experimental and may change at any time. Please do not depend on it. It may be enabled on an experimental basis by setting ---experimental_isolated_extension_usages If true, this usage of the module extension will be isolated from all other usages, both in this and other modules. Tags created for this usage do not affect other usages and the repositories generated by the extension for this usage will be distinct from all other repositories generated by the extension. This parameter is currently experimental and only available with the flag |
use_repo
None
use_repo(extension_proxy, *args, **kwargs)
Imports one or more repos generated by the given module extension into the scope of the current module.
Parameters
Parameter | Description |
---|---|
extension_proxy
|
required A module extension proxy object returned by a use_extension call.
|
args
|
required The names of the repos to import. |
kwargs
|
required Specifies certain repos to import into the scope of the current module with different names. The keys should be the name to use in the current scope, whereas the values should be the original names exported by the module extension. |
use_repo_rule
repo_rule_proxy use_repo_rule(repo_rule_bzl_file, repo_rule_name)Returns a proxy value that can be directly invoked in the MODULE.bazel file as a repository rule, one or more times. Repos created in such a way are only visible to the current module, under the name declared using the
name
attribute on the proxy. The implicit Boolean dev_dependency
attribute can also be used on the proxy to denote that a certain repo is only to be created when the current module is the root module.
Parameters
Parameter | Description |
---|---|
repo_rule_bzl_file
|
required A label to the Starlark file defining the repo rule. |
repo_rule_name
|
required The name of the repo rule to use. A symbol with this name must be exported by the Starlark file. |
