Is there a version of

file

or

resource

that allows pulling from a URL? I see

jvm_artifact

has a

url=

option for pulling third-party jars, and in a plugin you are given

DownloadFile

https://www.pantsbuild.org/docs/rules-api-file-system#downloadfile if you write a custom plugin

Hi! We'd be very happy to help out if you wanted to take a crack at implementing https://github.com/pantsbuild/pants/issues/13589

For more context: during a

package

step I have a mapping file generated by another team that needs to be included in the final artifact, but I don't want it committed my team's repo. They currently have it available at a URL (yay!) and today it's downloaded in a bash script

You could also use

experimental_shell_command

, I believe: https://www.pantsbuild.org/v2.10/docs/run-shell-commands

gotcha - so basically no it's not "supported" in the sense there's a way to do it

experimental_

stuff is usable, it just might not have a stable API yet, or it might be missing features or documentation.

The "experimental" part is solely to give us time to hear feedback from users before we stabilize the mechanism, like if we end up needing to redesign certain parts. We aren't obligated to follow the normal deprecation policy: https://www.pantsbuild.org/v2.10/docs/deprecation-policy, although we do make a best-effort attempt to still do so Several users have been using

experimental_shell_command

in production fine. Re

experimental_shell_command

vs the proposal at https://github.com/pantsbuild/pants/issues/13589, that ticket would give you a more first class way to do things. No need for you to define the

experimental_shell_command

logic which would probably need to do something like use

curl

, then would be good to use

shasum

to validate that the file is expected (supply chain attacks). Pants would do all that heavy lifting for you. Both work, but latter is more convenient

So it's supported in the practical sense of the word. We on Slack will provide support for it :)

gotcha, thanks for the clarification
