Users can set the field

output_path

(

OutputPathField

from

pants.core.goals.package

). Outside of users rewriting their BUILD files, there are two alternative approaches you can use in your plugin: 1. Use

dataclasses.replace()

on the

PackageFieldSet

objects that were resolved to replace the

output_path: OutputPathField

property. This is pretty hacky though - you can’t be sure that every single implementer of the

package

goal has implemented this field and put it in the

FieldSet

thing, and using that same attribute name of

output_path

2. After resolving the

packages

, each of the

BuiltPackage

will have a

digest: Digest

. You can use

RemovePrefix

on these to post-process the results (I don’t think

output_path

was added yet in b3 though)
