Possibility to download last available artifact from a workflow

[thebaptiste]

Hello
In my workflow 1 uploading my artifact, when the workflow succeed, sometimes a new artifact is uploaded, sometimes not (depending on the result of a given step : if the artifact is unchanged, it is not uploaded in order to avoid to create useless artifacts and spare space).
So, in my workflow 2 downloading my artifact, I would like to download the "latest artifact of the given name uploaded by a successful run of worflow 1 which produced an artifact" (this will not always be the last successful run of worfklow1, because it may not have uploaded any artifact).
I don't think it is possible for the time being. I think it would be an interesting feature.

I think it should be possible by not specifying pr, commit, branch and run_id.

See this workflow job:

action-download-artifact/.github/workflows/download.yml

Line 15 in 891ccce

download-latest:

Ok, great !
It didn't worked for me because :

• I had specified "branch" (because I want to do that on a given branch, but as the branch name is in my artifact name, it is not necessary)
• I had specified "workflow_conclusion: success" which was probably bringing the run number of the last successful run
  But without these two options it works.
  You can close my issue.

Thank you for your action that significantly improves the basic actions/download-artifact !

Sorry, I tried again, and it seems it doesn't work. It always try to download the artifact produced by the last run, and if this run did not produce any artifact, no artifact is downloaded.

[dawidd6]

Then I don't know.

@thebaptiste, @dawidd6 I have the same problem, it always downloads the artifact from the last execution, if I wanted to download another artifact without specifying the run_id, could we?

[dawidd6]

Can you elaborate?

[dawidd6]

Need more info (workflow runs, workflow files) so I can debug it further. Nothing can be done currently as I don't know much.

[rechemendia]

@dawidd6 I will try to explain more deeply.

In my case, every time I persist an artifact it is a release process that in turn publishes a staging, this artifact already carries the version number (<<project_name>>-v1.0.0), Obviously the version number and therefore the name of the artifact increases in each release process.

So when you publish to production it is another workflow that uses these artifacts ... and based on the version that you decide to publish, the download is requested, and this process is only working for the latest version and therefore it only downloads the artifact of the last workflow (release) executed.

We use it similar to this:

• make-release:
  

• publish-production:
  
  

I hope I have explained enough, however, if you need more, let me know.

Regards

Maybe specifying a commit would be helpful in your case? Still I would like to be able to browse the full repository and see how it works or not. Submitting a PR is an option too, if you can and verify that changes you made are indeed needed to make your workflow run as it should. Currently I'm not able to fully understand the issue.

[rechemendia]

@dawidd6 I will try to make a public repo to share this case and be able to understand better.

Seems like I'm facing a similar issue, I have

 name: Download
        uses: dawidd6/action-download-artifact@v2
        with:
          workflow: stage.yml
          name: github_run_number
          path: github_run_number
          workflow_conclusion: success

This is how my download section looks like,

I'm getting an older file downloaded instead of from the last successful build

[dawidd6]

Did this issue emerged for you only recently (like yesterday)?

[pjangam]

Yes. Today in fact.

[dawidd6]

Then it's a GitHub API issue, see: #57

[pjangam]

Okay. Thank you. FYI, I'm not getting errors, but the GitHub action is downloading older artifact instead of latest.
