hey is it possible to request using a generic Target when your object is a child of

Target

e.g.

files = await Get(SourceFiles, Target, target)

TypeError: Invalid Get. The third argument ... must have the exact same type as the second argument, <class 'pants.engine.target.Target'>, but had the type <class 'pants.backend.python.target_types.PythonTestTarget'>.

the code I have works in the goal rule, I just wanted to tidy up and extract into a separate rule. I know vaguely about the UnionRule, but I am not sure it can help me as I don't want to create new classes and register with

@union

, I want to union existing classes which are not decorated with

@union

and seems to be unusable. Does that make any sense?

can the type of

target

vary, or is it always going to be a

PythonTestTarget

?

it will vary, like 4-5 types (python_source, python_test, python_test_utils, plus a few custom ones)

besides unions, there’s also a lot of wrapper classes around to solve issues like these.. more on the returning side of things I beleive, but.. like WrappedTarget for instance.

yes,

await Get(Targets, Addresses([address]))

works 🙂
