🧩 I'm seeing this in my test:

E           ValueError: A target of type PexBinariesFromSourcesGeneratorTarget was proposed at address src/python/foo:pex_binaries with explicit sources main3.py, but this target type does not have a `sources` field.

But in

src/python/pants/backend/python/target_types.py

I have:

class PexBinariesFromSourcesGeneratingSourcesField(PythonGeneratingSourcesBase):
    ...

class PexBinariesFromSourcesGeneratorTarget(Target):
    alias = "pex_binaries_from_sources"
    core_fields = (
        ...
        PexBinariesFromSourcesGeneratingSourcesField,
    )

Yeah that's weird. Do you have a WIP PR you can push?

(one sec, getting auth issues, then I'll push)

I think I lean that way. I've been doing a rewrite of https://www.pantsbuild.org/v2.8/docs/targets and it's already tricky enough for users imo to understand targets. Here, the explictiness might be worth the clarity

That and I think the impl gets cleaner as well 😂

Oh sorry, miscommunication! I didn't realize you meant the old CAOF API. We're trying to actively kill that - it's not engine safe and does not hook into the file watcher. It's one of our most common confusions I thought you meant you were going to write an internal macro like these https://www.pantsbuild.org/v2.8/docs/macros

Oh man! There goes my work 😅
