protobuf_source

A single Protobuf file used to generate various languages.

See language-specific docs:
Python: Protobuf and gRPC
Go: Protobuf

Backend: pants.backend.codegen.protobuf.python

source

type: str
required

A single file that belongs to this target.

Path is relative to the BUILD file's directory, e.g. source='example.ext'.

dependencies

type: Iterable[str] | None
default: None

Addresses to other targets that this target depends on, e.g. ['helloworld/subdir:lib', 'helloworld/main.py:lib', '3rdparty:reqs#django'].

This augments any dependencies inferred by Pants, such as by analyzing your imports. Use ./pants dependencies or ./pants peek on this target to get the final result.

See Targets and BUILD files and Targets and BUILD files for more about how addresses are formed, including for generated targets. You can also run ./pants list :: to find all addresses in your project, or ./pants list dir: to find all addresses defined in that directory.

If the target is in the same BUILD file, you can leave off the BUILD file path, e.g. :tgt instead of helloworld/subdir:tgt. For generated first-party addresses, use ./ for the file path, e.g. ./main.py:tgt; for all other generated targets, use :tgt#generated_name.

You may exclude dependencies by prefixing with !, e.g. ['!helloworld/subdir:lib', '!./sibling.txt']. Ignores are intended for false positives with dependency inference; otherwise, simply leave off the dependency from the BUILD file.

description

type: str | None
default: None

A human-readable description of the target.

Use ./pants list --documented :: to see all targets with descriptions.

grpc

type: bool
default: False

Whether to generate gRPC code or not.

jvm_jdk

type: str | None
default: None
backend: pants.backend.experimental.codegen.protobuf.java

The major version of the JDK that this target should be built with. If not defined, will default to [jvm].default_source_jdk.

jvm_resolve

type: str | None
default: None
backend: pants.backend.experimental.codegen.protobuf.java

The resolve from [jvm].resolves to use when compiling this target.

If not defined, will default to [jvm].default_resolve.

python_interpreter_constraints

type: Iterable[str] | None
default: None
backend: pants.backend.codegen.protobuf.python

The Python interpreters this code is compatible with.

Each element should be written in pip-style format, e.g. CPython==2.7.* or CPython>=3.6,<4. You can leave off CPython as a shorthand, e.g. >=2.7 will be expanded to CPython>=2.7.

Specify more than one element to OR the constraints, e.g. ['PyPy==3.7.*', 'CPython==3.7.*'] means either PyPy 3.7 or CPython 3.7.

If the field is not set, it will default to the option [python].interpreter_constraints.

See Interpreter compatibility for how these interpreter constraints are merged with the constraints of dependencies.

python_resolve

type: str | None
default: None
backend: pants.backend.codegen.protobuf.python

The resolve from [python].resolves to use.

If not defined, will default to [python].default_resolve.

All dependencies must share the same value for their resolve field.

python_source_root

type: str | None
default: None
backend: pants.backend.codegen.protobuf.python

The source root to generate Python sources under.

If unspecified, the source root the protobuf_sources is under will be used.

skip_buf_format

type: bool
default: False
backend: pants.backend.codegen.protobuf.lint.buf

If true, don't run buf format on this target's code.

skip_buf_lint

type: bool
default: False
backend: pants.backend.codegen.protobuf.lint.buf

If true, don't run buf lint on this target's code.

tags

type: Iterable[str] | None
default: None

Arbitrary strings to describe a target.

For example, you may tag some test targets with 'integration_test' so that you could run ./pants --tag='integration_test' test :: to only run on targets with that tag.
