I’m writing a Pants plugin to infer some dependencies. In each directory, I have a

BUILD

file like follows in every directory.

python_sources(
    name="package_config",
    sources=[
        "_package_config.py",
    ],
)

python_sources()

Each directory containing a

BUILD

file with the

package_config

target name contains a corresponding

_package_config.py

file. My dependency inference rule (simplified) does something along the lines of this.

@rule(desc="...")
async def infer_dependencies(
    request: InferPackageConfigDependenciesRequest
) -> InferredDependencies:
    return InferredDependencies([Address("path/to/directory:package_config")])

I’m getting the following error when running

./pants dependees …

ResolveError: Directory 'path/to/directory:package_config' does not contain any BUILD files.

Is there a way to write my plugin such that it knows that I’m referring to a

python_sources

target, and not a directory?

the message seem to suggest there is no

path/to/directory/BUILD

file, so, where is your python_sources target defined?

I think I’m using the API incorrectly or it’s just confused. I’m providing

path/to/directory:package_config

to the

Address

constructor, and

path/to/directory:package_config

is a target defined in

path/to/directory/BUILD

ah, yes.. this

Address("path/to/directory:package_config")

should be

Address("path/to/directory", target_name="package_config")

Amazing!! Let me try that
