Hi, Can i reference a target from build BUILD file in another if those 2 BUILD files are in adjacent folders? My specific issue is that I have a (Python) package which has implicit dependencies on

.py

files in another package. I thought to solve this by adding the following target in the first BUILD file:

"dependencies": [
        ":second-package-sources",  # this refers to all of the '.py' files in the second package
    ],

":x" is a shortcut for targets defined in BUILD files in the same directory. For all others, use the full path from the build root, i.e.: "src/python/other/package/dir:second-packages-sources".

Ooh!

The full form is spelled out here: https://www.pantsbuild.org/docs/targets#target-addresses The abbreviated ":x" form is somewhat weirdly only called out later after switching to talking about sources and dependencies fields.

I see. Well, that solved it. Do you maybe know if there is a better solution for cases in which a package is a bundle of

py

files that are dynamically imported based an application conditions?

Nope, that's the most straightforward way. Everything else will probably be more complication than its worth.

dynamic string imports

Did you try?: https://www.pantsbuild.org/docs/reference-python-infer#string_imports

The strings are an input that are constructed dynamically too DX

depending on your use case, there’s support for stevedore plugins in pants most recent versions: https://github.com/pantsbuild/pants/pull/18132 may or may not be suitable for you..

Will take a look, thanks 🙂
