Restore OIDC trusted publishing for NuGet package publishing

[Copilot]

After @wokket properly reconfigured trusted publishing on NuGet.org following ownership changes, this PR restores OIDC-based authentication for NuGet package publishing.

Changes:

• Restored id-token: write permissions to build-netcore-tool and build-nuget-package jobs
• Restored NuGet/login@v1 OIDC authentication steps
• Updated dotnet nuget push commands to use OIDC-generated API key from steps.login.outputs.NUGET_API_KEY
• Fixed template expression spacing for consistency
• Cleaned up formatting and removed trailing whitespace

Before (API Key):

- name: Push to Nuget.org
  run: dotnet nuget push ... --api-key "${{ secrets.NUGET_API_KEY }}"

After (OIDC):

- name: NuGet login (OIDC → temp API key)
  uses: NuGet/login@v1
  id: login
  with:
    user: wokket
    
- name: Push to Nuget.org
  run: dotnet nuget push ... --api-key "${{ steps.login.outputs.NUGET_API_KEY }}"

OIDC trusted publishing is the preferred approach as it uses short-lived tokens instead of long-lived API key secrets.

Original prompt

The recent GitHub Actions job failed with a 401 error during the NuGet OIDC token exchange step, indicating that trusted publishing via OIDC is not currently working. Job logs: https://github.com/grate-devs/grate/actions/runs/20313888988/job/58352192590 (ref: 570787a).

Recent successful workflows suggest that classic NuGet API key publishing was previously used. To restore successful NuGet publishing, revert the job to use a classic NUGET_API_KEY secret.

Action steps:

1. Replace any publishing step using OIDC (trusted publishing/NUGET_AUTH_TOKEN) with classic API-key-based pushing, e.g.:

- name: Push to NuGet
  run: dotnet nuget push "*.nupkg" --source https://api.nuget.org/v3/index.json --api-key ${{ secrets.NUGET_API_KEY }}

2. Ensure the secret NUGET_API_KEY is referenced in the publish step.
3. Remove any unnecessary id-token: write permissions if present.

This change should restore the previous working behavior for package publishing until trusted publishing can be successfully reconfigured.

Feel free to revert this if you'd like, but Trusted Publishing seems to be the preferred option to avoid long-lived secrets. I think the configuration should now be updated for the new repo path etc.

I agree, I don't want to revert it long-term, but it looks like we _might_ need a publishing certificate to make this work (or I might mix things up). Anyways, I _have_ ordered a code signing cert, so we can start signing the NuGet packages soon too (even if that might be unrelated) ons. 17. des. 2025 kl. 22:36 skrev Tim Thompson ***@***.***>:

The Publish build still seems to fail in the main branch, @wokket . Have you done anything now today (night, whichever part of the day it is in your hemisphere :D) to fix things? The latest build of main failed due to some OIDC nuget auth failure.

Is this double slash in the URL correct? Or did someone add an extra slash (trailing or in the middle) here?

[wokket]

I reconfigured the trusted publishing info after the ownership changes to the DBMS packages last night (time zones are hard):

Whether those changes were in play last time you tried to push I'm not sure.

Hi @wokket , @erikbra
Can you guys add me to this repo, please? I will help to check the NuGet credentials. We should go with short live token anyway.

Thanks.

[erikbra]

I added you to this repo, @hoangthanh28 . Did it work?

I didn't have time to look more at this one today, sorry

Hi @erikbra
It's now getting 403 - which I'm not sure where is causing the issue. We might consider reverting the change (to use Nuget API key)/

@copilot rebase

Restored OIDC trusted publishing configuration in commit 1142b9f. Now that @wokket has properly configured trusted publishing on NuGet.org, this should resolve the authentication issues.

[hoangthanh28]

please remove it, we don't need this step. Will use the token when pushing to Nuget

[hoangthanh28]

Waiting for the final build to check.
