  # (e.g. an android_apk or a junit_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:
  #   deps: Specifies the input dependencies for this target.
  #
  #   build_config: Path to the .build_config file corresponding to the target.
  #
  #   android_manifest: Path to root manifest for the binary.
  #
  #   version_code: (optional)
  #
  #   version_name: (optional)
  #
  #   alternative_android_sdk_jar: Alternative system android.jar to use.
  #
  #   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_whitelist: (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.
  #
  #   support_zh_hk: (optional)
  #     If true, support zh-HK in Chrome on Android by using the resources
  #     from zh-TW. See https://crbug.com/780847.
  #
  #   aapt_locale_whitelist: (optional)
  #     Restrict compiled locale-dependent resources to a specific whitelist.
  #     NOTE: This is a list of Chromium locale names, not Android ones.
  #
  #   exclude_xxxhdpi: (optional)
  #
  #   xxxhdpi_whitelist: (optional)
  #
  #   no_xml_namespaces: (optional)
  #
  #   png_to_webp: (optional)
  #     If true, convert all PNG resources (except 9-patch files) to WebP.
  #
  #   post_process_script: (optional)
  #
  #   proto_format: (optional). If true, compiles resources into protocol
  #     buffer format.
  #
  # Output variables:
  #   output:  Path to a zip file containing the compiled resources.
  #
  #   r_text_out_path: (optional):
  #       Path for the corresponding generated R.txt file.
  #
  #   srcjar_path: (optional)
  #       Path to a generated .srcjar containing the generated R.java sources
  #       for all dependent resource libraries.
  #
  #   proguard_file: (optional)
  #       Path to proguard configuration file for this apk target.

  # Compile Java source files into a .jar file, potentially using an
  # annotation processor, and/or the errorprone compiler.
  #
  # 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 java_files / java_sources_file. The content
  # of the java_files list and the java_sources_file file must match exactly.
  # This rule uses java_files only to list the inputs to the action that
  # calls the javac.py script, but will pass the list of Java source files
  # with the '@${java_sources_file}" command-line syntax. Not a problem in
  # practice since this is only called from java_library_impl() that sets up
  # the variables properly.
  #
  # Variables:
  #  java_files: Optional list of Java source file paths.
  #  srcjar_deps: Optional list of .srcjar dependencies (not file paths).
  #    The corresponding source files they contain will be compiled too.
  #  srcjar_filearg: Optional @FileArg for additional srcjars.
  #  java_sources_file: Optional path to file containing list of Java source
  #    file paths. This must always be provided if java_files is not empty
  #    and must match it exactly.
  #  build_config: Path to the .build_config 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.
  #  alternative_android_sdk_ijar: Optional path to alternative Android system
  #    interface jar file (android.jar). Ignored it !requires_android.
  #  alternative_android_sdk_ijar_dep: If alternative_android_sdk_ijar is
  #    provided, this should be the dependency target that generates the
  #    alternative .jar file.
  #  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_incremental_javac_override: Optional. If provided, determines
  #    whether incremental javac compilation (based on jmake) is enabled.
  #    Otherwise, decision is based on the global enable_incremental_javac
  #    build arg variable.
  #  enable_errorprone: Optional. 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.
  #  apk_name: Optional APK name. If provided, will tell javac.py to also
  #    generate an .apk.jar.info file under size-info/${apk_name}.apk.jar.info
  #  provider_configurations: Optional list of paths to Java service
  #    provider configuration files [1]. These will be copied under
  #    META-INF/services/ in the final .jar file.
  #  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)
  #

  # A rule that will handle multiple Java-related targets.
  #
  # The caller can provide a list of source files with 'java_files'
  # and 'srcjar_deps', or a prebuilt .jar file through 'jar_path'.
  #
  # In the case of a 'java_binary' target type, it can even provide none of
  # that (and the rule will just generate its wrapper script).
  #
  # The template will process the input .jar file (either the prebuilt one,
  # or the result of compiling the sources), for example to apply Proguard,
  # but also other ranges of bytecode-level rewriting schemes.
  #
  # Variables:
  #  type: type of Java target, valid values: 'java_library', 'java_binary',
  #    'junit_binary', 'java_annotation_processor', and 'android_apk'
  #  main_target_name: optional. If provided, overrides target_name when
  #    creating sub-targets (e.g. "${main_target_name}__build_config") and
  #    some output files (e.g. "${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.
  #  java_files: Optional list of Java source file paths for this target.
  #  srcjar_deps: Optional list of .srcjar targets (not file paths). The Java
  #    source files they contain will also be compiled for this target.
  #  java_sources_file: Optional path to a file which will be written with
  #    the content of java_files. If not provided, the file will be written
  #    under $target_gen_dir/$main_target_name.sources. Ignored if
  #    java_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.
  #  final_jar_path: Optional path to the final output .jar file (after
  #    processing). If not provided, the output will go under
  #    $root_build_dir/lib.java/
  #  output_name: Optional output name for the final jar path. Ignored if
  #    final_jar_path is provided. Otherwise, used to determine the name
  #    of the final jar. If not provided, the default is to use the same
  #    name as jar_path, if provided, or main_target_name.
  #  dex_path: Optional. Path to the output dex.jar file for this target.
  #    Ignored if !supports_android.
  #  main_class: Main Java class name for 'java_binary', 'junit_binary' and
  #    'java_annotation_processor' target types. Should not be set for other
  #    ones.
  #  deps: Dependencies for this target.
  #  testonly: True iff target should only be used for tests.
  #  no_build_hooks: Disables bytecode rewriting of asserts and android
  #    resources methods.
  #  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).
  #  emma_never_instrument: Optional. If provided, whether to forbid
  #    instrumentation with the Emma coverage processor. If not provided,
  #    this is controlled by the global emma_coverage build arg variable
  #    and only used for non-test Chromium code.
  #  alternative_android_sdk_jar: Optional. Alternative Android system
  #    android.jar to use.
  #  alternative_android_sdk_ijar: Optional alternative Android system
  #    interface jar path (i.e. the alternative_android_sdk_jar file processed
  #    by the ijar tool).
  #  alternative_android_sdk_ijar_dep: Optional. Dependency target that
  #    generates alternative_android_sdk_ijar (if the latter is provided).
  #  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).
  #  classpath_deps: Optional list of additional java library dependencies,
  #    whose .jar files 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.
  #  bypass_platform_checks: Optional. If True, platform checks will not
  #    be performed. They are used to verify that every target with
  #    requires_android only depends on targets that, at least supports_android.
  #    Similarly, if a target has !supports_android, then it cannot depend on
  #    any other target that has requires_android.
  #  include_java_resources: Optional. If True, include Java (not Android)
  #    resources into final .jar file.
  #  android_manifest_for_lint: Optional path to Android manifest to use
  #    if Android linting is enabled. Ignored for 'android_apk' types
  #    (since the value of android_manifest will be used instead).
  #  lint_suppressions_file: Optional lint suppressions input 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.
  #
  # For 'android_apk' 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_allowed: Optional (default false). True to allow the
  #    generation of incremental APKs ('android_apk' targets only).
  #  incremental_apk_path: If incremental_allowed, path to the incremental
  #    output APK.
  #  incremental_install_json_path: If incremental_allowed, path to the output
  #    incremental install json configuration file.
  #  non_native_packed_relocations: Optional. True if the target Android
  #    system does not support compressed relocations in native shared
  #    libraries.
  #  shared_libraries_runtime_deps_file: Optional. Path to a file listing the
  #    native shared libraries required at runtime by
  #  secondary_abi_shared_libraries_runtime_deps_file:
  #
  #
  # For 'java_binary' and 'junit_binary' targets only. Ignored by others:
  #
  #  bootclasspath: Optional list of boot class paths used by the generated
  #    wrapper script.
  #  wrapper_script_name: Optional name for the generated wrapper script.
  #    Default is main target name.
  #  wrapper_script_args: Optional list of extra arguments used by the
  #    generated wrapper script.
