Implement fetch retry logic

Enhancement Request: Implement fetch retry logic

Summary

We see many transient failures in CI due to the inability to fetch packages or JAR files. Adding retry logic could help to reduce those failures.

Proposed Solution / Description

Add retry logic exponential backoff (e.g., up to 5 retries, pausing 4, 8, 16, 32, 64 seconds in-between tries before failing).

Additional Notes

• Review CI failures to see where the logic will be best deployed.
