are there any examples of associating a target with a target in a parent directory? (for context, this is for the Go plugin. I want to associate each

go_package

target with the nearest parent `go_module`target.)

Hm, we have code to look at ancestor files, which we then map to the owning target. https://github.com/pantsbuild/pants/blob/main/src/python/pants/backend/python/util_rules/ancestor_files.py https://github.com/pantsbuild/pants/blob/da780e27fd5b2e087fa454c9b2a865b14c845f7a/src/python/pants/backend/python/dependency_inference/rules.py#L203-L227 -- But I think probably what you really want is

AscendantAddresses

, which finds all ancestor targets: https://github.com/pantsbuild/pants/blob/da780e27fd5b2e087fa454c9b2a865b14c845f7a/src/python/pants/base/specs.py#L146-L150
