In our open source project, we are intermittently getting errors like these after moving from Jenkins to Github CI Actions:
More examples are documented in our Github Issues here: https://github.com/apache/pulsar/issues/6231
This issue almost seems related to this issue:
and this issue (about proxy settings):
Our Github workflow files are located here: https://github.com/apache/pulsar/tree/master/.github/workflows
This one, for example, has caused the issue: https://github.com/apache/pulsar/blob/master/.github/workflows/ci-unit-flaky.yaml
How do we resolve this issue?
I tested on the forked repository of your repository, but did not reproduce the problem, it always can work without errors.
Maybe you can try to enabling debug logging on your repository, and share the detailed debug logs with us if the error occurs again next time.
I am getting similar errors intermittently on a private Jenkins instance; same maven repository, different packages. Maybe the problem is with Apache's server?
