#21093 retry on downloading files server errors Issue created by cburroughs Is your feature request related to a problem? Please describe. We have recently seen a CI job fail along the lines of:

00:14:03.03 [ERROR] 1 Exception encountered:
Engine traceback:
  in `lint` goal
IntrinsicError: Server error (502) downloading file helm-unittest-linux-amd64-0.3.3.tgz from <https://github.com/helm-unittest/helm-unittest/releases/download/v0.3.3/helm-unittest-linux-amd64-0.3.3.tgz>

This is almost certainly a transient error. Describe the solution you'd like Some amount of retry/backoff for this class of errors. Describe alternatives you've considered Retry the entire CI job on any error. Besides using a lot more compute, I would prefer to avoid treats invocations of

pants

as flaky things that need retry-wrappers. Additional context

src/rust/engine/src/downloads.rs

has a variety of references to retries already, but I don't read Rust well enough to be clear on the current state. pantsbuild/pants
