# Self-Healing CI: Auto-Retrying a Maven Central Timeout

> A timeout pulling an artifact from Maven Central is a transient transport blip, not a missing dependency. See the manual fix and how self-healing CI retries the resolve.

A Maven resolve that times out fetching a jar hit a slow or congested repository moment, not a broken dependency -- the same coordinate resolves on a retry.

## What makes a failure safely retryable

Automatic retry is only correct for failures that are genuinely transient. Retrying a deterministic failure wastes minutes and hides a real defect, so the classification matters more than the retry mechanism.

- Safe to retry: network timeouts, registry 5xx, transient DNS failures, a service container that was not ready, a spot instance reclaimed mid-run.
- Not safe to retry: assertion failures, compile errors, lint violations, anything that fails identically on every attempt.
- Ambiguous, and worth investigating rather than retrying: out-of-memory kills, disk exhaustion, and flaky tests. These repeat under load and a retry only hides the trend.
- Always record that a retry happened. A pipeline that silently retries is a pipeline whose real failure rate you do not know.

## FAQ

### What causes Self-Healing CI: Auto-Retrying a Maven central timeout?

A Maven build fails because resolving a dependency from Maven Central timed out or reset mid-download. The coordinate is valid and the artifact exists; the request hit a congested repository or a brief network blip. A human re-runs the build and the same dependency resolves cleanly.

### How do I fix Self-Healing CI: Auto-Retrying a Maven central timeout manually?

[object Object]

### Can Self-Healing CI: Auto-Retrying a Maven central timeout be fixed automatically?

A Maven Central timeout carries a recognizable transient signature -- a timeout or reset on a transfer, not a 404 -- and the safe response is to retry the resolve, ideally onto a mirror. A self-healing CI pipeline detects the download failure, retries dependency resolution, and only escalates if the coordinate is genuinely missing,
