| Installation |
| ------------ |
| |
| The Java module can be installed by adding the following lines to your MODULE.bazel file, replacing the version number placeholder with the desired version: |
| |
| .. code-block:: python |
| |
| bazel_dep(name = "rules_proto_grpc_java", version = "<version number here>") |
| |
| .. _java_proto_compile: |
| |
| java_proto_compile |
| ------------------ |
| |
| Generates a Java protobuf srcjar file |
| |

| * - Name |
| - Type |
| - Mandatory |
| - Default |
| - Description |
| * - ``protos`` |
| - ``label_list`` |
| - true |
| - |
| - List of labels that provide the ``ProtoInfo`` provider (such as ``proto_library`` from ``@protobuf``) |
| * - ``options`` |
| - ``string_list_dict`` |
| - false |
| - ``[]`` |
| - Extra options to pass to plugins, as a dict of plugin label -> list of strings. The key * can be used exclusively to apply to all plugins |
| * - ``verbose`` |
| - ``int`` |
| - false |
| - ``0`` |
| - The verbosity level. Supported values and results are 0: Show nothing, 1: Show command, 2: Show command and sandbox after running protoc, 3: Show command and sandbox before and after running protoc, 4. Show env, command, expected outputs and sandbox before and after running protoc |
| * - ``prefix_path`` |
| - ``string`` |
| - false |
| - ``""`` |
| - Path to prefix to the generated files in the output directory |
| * - ``extra_protoc_args`` |
| - ``string_list`` |
| - false |
| - ``[]`` |
| - A list of extra command line arguments to pass directly to protoc, not as plugin options |
| * - ``extra_protoc_files`` |

| - List of labels that provide extra files to be available during protoc execution |
| * - ``output_mode`` |
| - ``string`` |
| - false |
| - ``PREFIXED`` |
| - The output mode for the target. PREFIXED (the default) will output to a directory named by the target within the current package root, NO_PREFIX will output directly to the current package. Using NO_PREFIX may lead to conflicting writes |
