Troubleshooting GitHub workflow uploading to GH packages having a time-out

Body

I have an open source project hosted on GitHub. The GH workflow builds the project successfully, but deploying to GitHub packages does no longer work for some reason. I get a time-out while uploading a small pom file.

Failed workflow run: https://github.com/advantest/flexmark-java/actions/runs/18785300647

The error message in the logs is the following:

...

This same workflow did successfully deploy to GitHub pages and AFAIK the workflow did not change since then.

Does someone has any idea why the deployment now fails? Thank you for any help.

I have had this issue in the past where re-running the workflow or bumping release version resolved the issue.

Otherwise, i think it is recommended to use GitHub workflow with project workspace, settings.xml, & GH token for mvn commands package & deploy via maven/gradle wrappers.

Workflow Snippet

- name: Build with Maven
      run: ./mvnw -B package --file pom.xml

- name: Publish to GitHub Packages Apache Maven
  run: ./mvnw deploy -s $GITHUB_WORKSPACE/settings.xml
  env:
    GITHUB_TOKEN: ${{ github.token }}

See sample packages here that may help narrow the issue:

• https://github.com/conorheffron/ironoc/blob/main/.github/workflows/maven-publish.yml (Maven)
• https://github.com/conorheffron/ironoc-db/blob/main/.github/workflows/gradle-publish.yml (Gradle with maven-publish plugin)
• https://github.com/conorheffron?tab=packages (Maven / Apache Packages available here for projects ironoc & ironoc-db)

Note: It might be worth separating publish workflow from running CI steps (such as install test, test coverage etc. to isolate the issue - that is a lot for one workflow, might be a natural timeout for bigger project with many sub modules)

Thank you for the hints @conorheffron,
I started the failed deployment job again and it did not fail this time. I did not change anything. It seems, there have been a temporary issue on GitHub.
