What’s the cleanest way to go from target address to outputted package file path? Essentially, so that I can utilise Pant’s internal check for “does .pex exist already in the place where I would expect it to be output?“. It seems the mapping is simply:

<dir-path>:<target-name>

is output to

dist/<dir-path>/<target-name>.pex

, but is there a way I can use this logic directly?

Use

pants peek TARGET

and look at the

output_path

field's value.

Strangely, mine is

"output_path": null,

, but that may be because i’m on an older version of Pants

What Pants version are you using?

2.17 still, lagging behind

Looks like it’s only generated on certain goals and I may have to re-implement the logic
