These are the basic functions to get started.
To use these functions, load them at the top of your BUILD file. For example:
load("@rules_jvm_external//:defs.bzl", "maven_install", "artifact")javadoc(name, deps, javadocopts)
Generate a javadoc from all the deps
ATTRIBUTES
| Name | Description | Type | Mandatory | Default |
|---|---|---|---|---|
| name | A unique name for this target. | Name | required | |
| deps | The java libraries to generate javadocs for. The source jars of each dep will be used to generate the javadocs. Currently docs for transitive dependencies are not generated. |
List of labels | required | |
| javadocopts | javadoc options. Note sources and classpath are derived from the deps. Any additional options can be passed here. | List of strings | optional | [] |
java_export(name, maven_coordinates, deploy_env, pom_template, visibility, tags, kwargs)
Extends java_library to allow maven artifacts to be uploaded.
This macro can be used as a drop-in replacement for java_library, but
also generates an implicit name.publish target that can be run to publish
maven artifacts derived from this macro to a maven repository. The publish
rule understands the following variables (declared using --define when
using bazel run):
maven_repo: A URL for the repo to use. May be "https" or "file".maven_user: The user name to use when uploading to the maven repository.maven_password: The password to use when uploading to the maven repository.
This macro also generates a name-pom target that creates the pom.xml file
associated with the artifacts. The template used is derived from the (optional)
pom_template argument, and the following substitutions are performed on
the template file:
{groupId}: Replaced with the maven coordinates group ID.{artifactId}: Replaced with the maven coordinates artifact ID.{version}: Replaced by the maven coordinates version.{type}: Replaced by the maven coordintes type, if present (defaults to "jar"){dependencies}: Replaced by a list of maven dependencies directly relied upon by java_library targets within the artifact.
The "edges" of the artifact are found by scanning targets that contribute to runtime dependencies for the following tags:
maven_coordinates=group:artifact:type:version: Specifies a dependency of this artifact.maven:compile_only: Specifies that this dependency should not be listed as a dependency of the artifact being generated.
To skip generation of the javadoc jar, add the no-javadocs tag to the target.
Generated rules:
name: Ajava_librarythat other rules can depend upon.name-docs: A javadoc jar file.name-pom: The pom.xml file.name.publish: To be executed bybazel runto publish to a maven repo.

maven_install(name, repositories, artifacts, fail_on_missing_checksum, fetch_sources, fetch_javadoc, use_unsafe_shared_cache, excluded_artifacts, generate_compat_repositories, version_conflict_policy, maven_install_json, override_targets, strict_visibility, resolve_timeout, jetify, jetify_include_list, additional_netrc_lines, fail_if_repin_required, use_starlark_android_rules, aar_import_bzl_label, duplicate_version_warning)
Resolves and fetches artifacts transitively from Maven repositories.
This macro runs a repository rule that invokes the Coursier CLI to resolve and fetch Maven artifacts transitively.
PARAMETERS
| Name | Description | Default Value |
|---|---|---|
| name | A unique name for this Bazel external repository. | "maven" |
| repositories | A list of Maven repository URLs, specified in lookup order. Supports URLs with HTTP Basic Authentication, e.g. "https://username:password@example.com". |
[] |
| artifacts | A list of Maven artifact coordinates in the form of group:artifact:version. |
[] |
| fail_on_missing_checksum | - |
True |
| fetch_sources | Additionally fetch source JARs. | False |
| fetch_javadoc | Additionally fetch javadoc JARs. | False |
| use_unsafe_shared_cache | Download artifacts into a persistent shared cache on disk. Unsafe as Bazel is currently unable to detect modifications to the cache. | False |
| excluded_artifacts | A list of Maven artifact coordinates in the form of group:artifact to be excluded from the transitive dependencies. |
[] |
| generate_compat_repositories | Additionally generate repository aliases in a .bzl file for all JAR artifacts. For example, @maven//:com_google_guava_guava can also be referenced as @com_google_guava_guava//jar. |
False |
| version_conflict_policy | Policy for user-defined vs. transitive dependency version conflicts. If "pinned", choose the user's version unconditionally. If "default", follow Coursier's default policy. | "default" |
| maven_install_json | A label to a maven_install.json file to use pinned artifacts for generating build targets. e.g //:maven_install.json. |
None |
| override_targets | A mapping of group:artifact to Bazel target labels. All occurrences of the target label for group:artifact will be an alias to the specified label, therefore overriding the original generated jvm_import or aar_import target. |
{} |
| strict_visibility | Controls visibility of transitive dependencies. If True, transitive dependencies are private and invisible to user's rules. If False, transitive dependencies are public and visible to user's rules. |
False |
| resolve_timeout | The execution timeout of resolving and fetching artifacts. | 600 |
| jetify | Runs the AndroidX Jetifier tool on artifacts specified in jetify_include_list. If jetify_include_list is not specified, run Jetifier on all artifacts. | False |
| jetify_include_list | List of artifacts that need to be jetified in groupId:artifactId format. By default all artifacts are jetified if jetify is set to True. |
["*"] |
| additional_netrc_lines | Additional lines prepended to the netrc file used by http_file (with maven_install_json only). |
[] |
| fail_if_repin_required | Whether to fail the build if the required maven artifacts have been changed but not repinned. Requires the maven_install_json to have been set. |
False |
| use_starlark_android_rules | Whether to use the native or Starlark version of the Android rules. Default is False. | False |
| aar_import_bzl_label | The label (as a string) to use to import aar_import from. This is usually needed only if the top-level workspace file does not use the typical default repository name to import the Android Starlark rules. Default is "@build_bazel_rules_android//rules:rules.bzl". | "@build_bazel_rules_android//android:rules.bzl" |
| duplicate_version_warning | What to do if an artifact is specified multiple times. If "error" then fail the build, if "warn" then print a message and continue, if "none" then do nothing. The default is "warn". | "warn" |
These are helper functions to specify more information about Maven artifacts and
repositories in maven_install.
To use these functions, load the maven struct at the top of your BUILD file:
load("@rules_jvm_external//:specs.bzl", "maven")maven.repository(url, user, password)
Generates the data map for a Maven repository specifier given the available information.
If both a user and password are given as arguments, it will include the access credentials in the repository spec. If one or both are missing, it will just generate the repository url.
PARAMETERS
| Name | Description | Default Value |
|---|---|---|
| url | A string containing the repository url (ex: "https://maven.google.com/"). | none |
| user | A username for this Maven repository, if it requires authentication (ex: "johndoe"). | None |
| password | A password for this Maven repository, if it requires authentication (ex: "example-password"). | None |
maven.artifact(group, artifact, version, packaging, classifier, override_license_types, exclusions, neverlink, testonly)

| artifact | The Maven artifact coordinate artifact name (ex: "guava"). | none |
| version | The Maven artifact coordinate version name (ex: "27.0-jre"). | none |
| packaging | The Maven packaging specifier (ex: "jar"). | None |
| classifier | The Maven artifact classifier (ex: "javadoc"). | None |
| override_license_types | An array of Bazel license type strings to use for this artifact's rules (overrides autodetection) (ex: ["notify"]). | None |

| neverlink | Determines if this artifact should be part of the runtime classpath. | None |
| testonly | Determines whether this artifact is available for targets not marked as testonly = True. |
None |
maven.exclusion(group, artifact)
Generates the data map for a Maven artifact exclusion.
