  # A template that is used to compile all resources needed by a binary
  # (e.g. an android_apk or a robolectric_binary) into an intermediate .ar_
  # archive. It can also generate an associated .srcjar that contains the
  # final R.java sources for all resource packages the binary depends on.
  #
  # Input variables:
  #   android_sdk_dep: The sdk dep that these resources should compile against.
  #
  #   deps: Specifies the input dependencies for this target.
  #
  #   build_config: Path to the .build_config.json file corresponding to the target.
  #
  #   build_config_dep: Dep target to generate the .build_config.json file.
  #
  #   android_manifest: Path to root manifest for the binary.
  #
  #   version_code: (optional)
  #
  #   version_name: (optional)
  #
  #   shared_resources: (optional)
  #     If true, make all variables in each generated R.java file non-final,
  #     and provide an onResourcesLoaded() method that can be used to reset
  #     their package index at load time. Useful when the APK corresponds to
  #     a library that is loaded at runtime, like system_webview_apk or
  #     monochrome_apk.
  #
  #   app_as_shared_lib: (optional)
  #     If true, same effect as shared_resources, but also ensures that the
  #     resources can be used by the APK when it is loaded as a regular
  #     application as well. Useful for the monochrome_public_apk target
  #     which is both an application and a shared runtime library that
  #     implements the system webview feature.
  #
  #   shared_resources_allowlist: (optional)
  #     Path to an R.txt file. If provided, acts similar to shared_resources
  #     except that it restricts the list of non-final resource variables
  #     to the list from the input R.txt file. Overrides shared_resources
  #     when both are specified.
  #
  #   shared_resources_allowlist_locales: (optional)
  #     If shared_resources_allowlist is used, provide an optional list of
  #     Chromium locale names to determine which localized shared string
  #     resources to put in the final output, even if aapt_locale_allowlist
  #     is defined to a smaller subset.
  #
  #   aapt_locale_allowlist: (optional)
  #     Restrict compiled locale-dependent resources to a specific allowlist.
  #     NOTE: This is a list of Chromium locale names, not Android ones.
  #
  #   r_java_root_package_name: (optional)
  #     Short package name for this target's root R java file (ex. input of
  #     "base" would become "gen.base_module" for the root R java package name).
  #     Optional as defaults to "base".
  #
  #   resource_exclusion_regex: (optional)
  #
  #   resource_exclusion_exceptions: (optional)
  #
  #   resource_values_filter_rules: (optional)
  #
  #   png_to_webp: (optional)
  #     If true, convert all PNG resources (except 9-patch files) to WebP.
  #
  #   post_process_script: (optional)
  #
  #   package_name: (optional)
  #     Name of the package for the purpose of creating R class.
  #
  #   package_id: (optional)
  #     Use a custom package ID in resource IDs.
  #
  #   arsc_package_name: (optional)
  #     Use this package name in the arsc file rather than the package name
  #     found in the AndroidManifest.xml. Does not affect the package name
  #     used in AndroidManifest.xml.
  #
  #   resource_ids_provider_dep: (optional)
  #     Use resource IDs provided by another APK target when compiling resources
  #     (via. "aapt2 link --stable-ids")
  #
  #
  # Output variables:
  #   arsc_output: Path to output .ap_ file (optional).
  #
  #   proto_output: Path to output .proto.ap_ file (optional).
  #
  #   r_text_out_path: (optional):
  #       Path for the corresponding generated R.txt file.
  #
  #   proguard_file: (optional)
  #       Path to proguard configuration file for this apk target.

  # annotation processor, and/or the errorprone compiler. Also includes Kotlin
  # source files in the resulting info file.
  #
  # Note that the only way to specify custom annotation processors is
  # by using build_config to point to a file that corresponds to a java-related
  # target that includes javac:processor_classes entries (i.e. there is no
  # variable here that can be used for this purpose).
  #
  # Note also the peculiar use of source_files / target_sources_file. The content
  # of the source_files list and the source files in target_sources_file file must
  # match exactly.
  #
  # Variables:
  #  main_target_name: Used when extracting srcjars for codesearch.
  #  source_files: Optional list of Java and Kotlin source file paths.
  #  srcjar_deps: Optional list of .srcjar dependencies (not file paths).
  #    The corresponding source files they contain will be compiled too.
  #  target_sources_file: Optional path to file containing list of source file
  #    paths. This must always be provided if java_files is not empty and the
  #    .java files in it must match the list of java_files exactly.
  #  build_config: Path to the .build_config.json file of the corresponding
  #    java_library_impl() target. The following entries will be used by this
  #    template: javac:srcjars, deps_info:javac_full_classpath,
  #    deps_info:javac_full_interface_classpath, javac:processor_classpath,
  #    javac:processor_classes
  #  javac_jar_path: Path to the final output .jar file.
  #  javac_args: Optional list of extra arguments to pass to javac.
  #  chromium_code: Whether this corresponds to Chromium-specific sources.
  #  requires_android: True if these sources can only run on Android.
  #  additional_jar_files: Optional list of files to copy into the resulting
  #    .jar file (by default, only .class files are put there). Each entry
  #    has the 'srcPath:dstPath' format.
  #  enable_errorprone: If True, use the errorprone compiler to check for
  #    error-prone constructs in the language. If not provided, whether this is
  #    enabled depends on chromium_code and the global
  #    use_errorprone_java_compiler variable.
  #  use_turbine: If True, compile headers using turbine.py.
  #  apk_name: Optional APK name. If provided, will tell compile_java.py to also
  #    generate an .apk.jar.info file under size-info/${apk_name}.apk.jar.info
  #  processor_args_javac: List of annotation processor arguments, each one
  #    will be passed to javac as -A<entry>.
  #  deps: Dependencies for the corresponding target.
  #  testonly: Usual meaning (should be True for test-only targets)

  #
  # Variables:
  #  type: type of Java target, valid values: 'java_library', 'java_binary',
  #    'robolectric_binary', 'java_annotation_processor', and 'android_apk'
  #  main_target_name: optional. If provided, overrides target_name when
  #    creating sub-targets (e.g. "${main_target_name}__dex") and
  #    some output files (e.g. "${main_target_name}.sources"). Only used
  #    for 'android_apk' types at the moment, where main_target_name will
  #    be the name of the main APK target.
  #  supports_android: Optional. True if target can run on Android.
  #  requires_android: Optional. True if target can only run on Android.
  #  source_files: Optional list of Java source file paths for this target.
  #  javac_args: Optional list of extra arguments to pass to javac.
  #  errorprone_args: Optional list of extra arguments to pass to.
  #  srcjar_deps: Optional list of .srcjar targets (not file paths). The Java
  #    source files they contain will also be compiled for this target.
  #  target_sources_file: Optional path to a file which will be written with
  #    the content of source_files. If not provided, the file will be written
  #    under $target_gen_dir/$main_target_name.sources. Ignored if
  #    sources_files is empty. If not
  #  jar_path: Optional path to a prebuilt .jar file for this target.
  #    Mutually exclusive with java_files and srcjar_deps.
  #  output_name: Optional output name for the final jar path. Used to
  #    determine the name of the final jar. Default is to use the same
  #    name as jar_path, if provided, or main_target_name.
  #  main_class: Main Java class name for 'java_binary', 'robolectric_binary' and
  #    'java_annotation_processor' target types. Should not be set for other
  #    ones.
  #  deps: Dependencies for this target.
  #  public_deps: Dependencies that this target exposes as part of its public API.
  #    public_deps do not need to be listed in both the 'deps' and 'public_deps' lists.
  #  testonly: True iff target should only be used for tests.
  #  chromium_code: Optional. Whether this is Chromium-specific code. If not
  #    provided, this is determined automatically, based on the location of
  #    the source files (i.e. anything under third_party/ is not
  #    Chromium-specific unless it is in a 'chromium' sub-directory).
  #  jacoco_never_instrument: Optional. If provided, whether to forbid
  #    instrumentation with the Jacoco coverage processor. If not provided,
  #    this is controlled by the global use_jacoco_coverage build arg variable
  #    and only used for non-test Chromium code.
  #  include_android_sdk: Optional. Whether or not the android SDK dep
  #    should be added to deps. Defaults to true for non-system libraries
  #    that support android.
  #  alternative_android_sdk_dep: Optional. Alternative Android system
  #    android java target to use.
  #  annotation_processor_deps: Optional list of dependencies corresponding
  #    to annotation processors used to compile these sources.
  #  input_jars_paths: Optional list of additional .jar file paths, which will
  #    be added to the compile-time classpath when building this target (but
  #    not to the runtime classpath).
  #  gradle_treat_as_prebuilt: Cause generate_gradle.py to reference this
  #    library via its built .jar rather than including its .java sources.
  #  proguard_enabled: Optional. True to enable ProGuard obfuscation.
  #  proguard_configs: Optional list of additional proguard config file paths.
  #  is_robolectric: Optional. If True, this is a host side android test binary
  #    which is allowed to depend on other android targets.
  #  include_java_resources: Optional. If True, include Java (not Android)
  #    resources into final .jar file.
  #  jar_excluded_patterns: Optional list of .class file patterns to exclude
  #    from the final .jar file.
  #  jar_included_patterns: Optional list of .class file patterns to include
  #    in the final .jar file. jar_excluded_patterns take precedence over this.
  #  low_classpath_priority: Indicates that the library should be placed at the
  #    end of the classpath. The default classpath order has libraries ordered
  #    before the libraries that they depend on. 'low_classpath_priority' is
  #    useful when one java_library() overrides another via
  #    'jar_excluded_patterns' and the overriding library does not depend on the
  #    overridee.
  #
  # For 'android_apk' and 'android_app_bundle_module' targets only:
  #
  #  apk_path: Path to the final APK file.
  #  android_manifest: Path to AndroidManifest.xml file for the APK.
  #  android_manifest_dep: Optional. Dependency target that generates
  #    android_manifest.
  #  apk_under_test: For 'android_apk' targets used to test other APKs,
  #    this is the target name of APK being tested.
  #  incremental_apk_path: Path to the incremental APK.
  #  incremental_install_json_path: Path to the incremental install json.
  #  native_lib_placeholders: Optional. List of placeholder filenames to add to
  #    the APK.
  #  proguard_mapping_path: Path to .mapping file produced from ProGuard step.
  #  shared_libraries_runtime_deps_file: Optional. Path to a file listing the
  #    native shared libraries required at runtime by the APK.
  #  secondary_abi_shared_libraries_runtime_deps_file:
  #  secondary_native_lib_placeholders: Optional. List of placeholder filenames
  #    to add to the APK for the secondary ABI.
  #  loadable_modules: Optional list of extra native libraries to
  #    be stored in the APK.
  #  secondary_abi_loadable_modules: Optional list of native libraries for
  #    secondary ABI.
  #  proto_resources_path: The path of an zip archive containing the APK's
  #    resources compiled to the protocol buffer format (instead of regular
  #    binary xml + resources.arsc).
  #  r_text_path: The path of the R.txt file generated when compiling the
  #    resources for this target.
  #  module_pathmap_path: The path of the pathmap file generated when compiling
  #    the resources for the bundle module, if path shortening is enabled.
  #  base_allowlist_rtxt_path: The path of the R.txt file containing the
  #    list of string resources to keep in the base split APK for any bundle
  #    that uses this target.
  #

# Create a zip archive corresponding to an application bundle module.
#
# Compile all the components of a given android_apk_or_module() target into a
# zip archive suitable to later create an android_app_bundle() target. This
# archive's format is very similar to that on an APK, except for a few
# differences in internal directory layouts, and the fact that resources, as
# well as xml files, are compiled using a protocol-buffer based format (instead
# of the regular binary xml + resources.arsc).
#
# A final application bundle is built from one or more module bundle modules,
# plus some configuration file.
#
# Variables:
#   module_zip_path: Output module path.
#   build_config: Path to build_config of the android_apk_or_module() target.
#   dex_path: If module is proguarded separately from the base module, dex_path
#     is the path to its dex file and is passed directly to the creation script.
#     Otherwise, dex_path is undefined and we retrieve the module's dex file
#     using its build_config.
#   expected_libs_and_assets: Verify the list of included native libraries
#     and assets is consistent with the given expectation file.
#   expected_libs_and_assets_base: Treat expected_libs_and_assets as a diff
#     with this file as the base.
#   is_multi_abi: If true will add a library placeholder for the missing ABI if
#     either the primary or the secondary ABI has no native libraries set.
#   module_name: The module's name.
#   native_libraries_config: Path to file listing native libraries to be
#     packaged into each module.
#   proguard_enabled: Optional. True if proguarding is enabled for this
#     bundle. Default is to enable this only for release builds. Note that
#     this will always perform synchronized proguarding.
