# Self-Healing CI: Recovering a Failed Gradle Distribution Download

> A failed Gradle wrapper distribution download is a transient fetch problem, not a build-script bug. See the manual fix and how self-healing CI retries the download.

A Gradle wrapper that cannot download its distribution hit a network blip on a large fetch at setup, not a broken build -- the same distribution downloads 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: recovering a failed Gradle distribution download?

A Gradle build fails before any task runs because the wrapper could not download the Gradle distribution -- a timeout, reset, or partial transfer. The distribution URL is valid and the version exists; the large fetch hit a transient network problem. A human re-runs the job and the wrapper provisions cleanly.

### How do I fix Self-Healing CI: recovering a failed Gradle distribution download manually?

[object Object]

### Can Self-Healing CI: recovering a failed Gradle distribution download be fixed automatically?

A failed distribution download has a recognizable transient signature -- a timeout or partial transfer on a large fetch at setup -- and the safe response is to retry, ideally from a cache. A self-healing CI pipeline detects the provisioning failure, retries the download, and only escalates if the distribution is genuinely unreachable
