Question

A workflow uses a build matrix across `os: [ubuntu-latest, windows-latest, macos-latest]` and `node: [18, 20]`, producing six jobs. After a run completes, only the job labeled `build (windows-latest, 20)` has failed due to a flaky network timeout, while the other five passed. You want to retry just that one variant without consuming minutes on the passing jobs. What is the most efficient way to do this from the UI?

Accepted Answer

Open the failed run and click 'Re-run failed jobs', which re-runs only the jobs that did not succeed.

Answer

Click 'Re-run all jobs', because matrix jobs can only be re-run together as a single unit.

Answer

Edit the matrix in the YAML to temporarily exclude the five passing combinations, then push a commit to trigger a new run.

Answer

Cancel the completed run and use `workflow_dispatch` to start a fresh run of the entire workflow.
