What would be the cleanest way to add to the dependency graph that Pants uses with the

--changed-since

flag? I can of course extract that logic with

pants list --changed-since ::

and append items, but is there a nice way to provide key value pairs to this graph e.g.

arbritary_file.txt: ["other", "dependent", "files"]

If I'm understanding the question correctly..., I think you could use the

dependencies

option on the target Here's an example.. Folder structure (both text files are empty)

pants-example
├── BUILD
├── example1.txt
└── example2.txt

The BUILD file:

file(
  name="example1",
  source="example1.txt",
  dependencies=[":example2"]
)

file(
  name="example2",
  source="example2.txt",
)

and using

pants filedeps

to see the dependencies:

$ pants filedeps --filedeps-transitive pants-example/example1.txt
pants-example/BUILD
pants-example/example1.txt
pants-example/example2.txt

Ah that is useful to know. Thanks! What’s the closest I could get to a

dir -> target

relationship here? e.g. in the case of multiple dirs containing Dockerfiles which aren’t handled by Pants targets, I’ll like to explicitly set target dependencies

np! Perhaps

target(...)

might help get what you want https://www.pantsbuild.org/dev/reference/targets/target
