actions/download-artifact for GHE environment

[andreineculau]

using v3 fails actionlint with

the runner of "actions/upload-artifact@v3" action is too old to run on GitHub Actions. update the action's version to fix this issue [action]

but actions/upload-artifact@v4 cannot be used on GHES

Warning: Artifact upload failed with error: GHESNotSupportedError: @actions/artifact v2.0.0+, upload-artifact@v4+ and download-artifact@v4+ are not currently supported on GHES..

Can we add a special condition?

Same for artifact-upload

I have no idea because I don't have a GHE environment with GitHub Actions enabled. One obvious workaround for this is ignoring the erorr by regular expressions as desribed in the v1.7.4 releae note.

Before considering to add some special handling for this, I'd like to ask some questions to understand the situation better.

• actions/upload-artifact@v3 will be unavailable soon because node16 will be dropped on Nov. 12.
  • Will actions/upload-artifact@v4 support GHE in the time frame?
  • Or will GHE continue to support node16 runner with actions/upload-artifact@v4 being unsupported in long term?
• Is there any good document which describes what runners are supported on GHE (if supported runners are different from the github.com environment)?

I'm a bit confused because they announce that actions/upload-artifact@v4 doesn't support GHE but actions/upload-artifact@v3 is deprecated.

I found v3-node20. Is it what you should use?

• https://github.com/actions/download-artifact/releases/tag/v3-node20

Cool. What we have done temporarily is to use the commit hash pointing to the current v3 (at the expense of maybe failing to keep up to the date with v3 patches). I didn't know about the v3-node20 versions 🙌

I'm a bit confused because they announce that actions/upload-artifact@v4 doesn't support GHE but actions/upload-artifact#635.

There's some info related to roadmap here actions/upload-artifact#537 - tl;dr v3 will be deprecated but will still run on GHES moving forward, with the expectation that v4 will be supported Q1 2025

Not sure what you mean. On GHES you only have self-hosted runners AFAIK, so anything goes.

Yeah, I don't know how it is maintained. However v3 is deprecated and I don't think new features will be added.

Thank you for the information. Then I believe v3/node20 branch will be maintained until v4 supports GHES. v3 cannot be upgraded to node20 runner because it breaks the compatibility. And v4 is not supporting GHES yet. Maintaining v3/node20 is the only way to support GHES.

I didn't know that GHES only supports self-hosted runners. As I said above, I don't have GHES environment hence I don't know the specs at all. Thanks for explaining that 👍

I'm closing this because actions/download-artifact@v3-node20 is the current solution.
