Retry downloading required test artifacts with a backoff when download fails.

When Maven fails to download a required artifact for a test, the test fails. Is it possible to configure Maven to retry the download with a backoff up to N number of attempts?

Example test failure:

No source file or test is named. Start by inspecting the Beam Maven build and the Jenkins failure linked in the issue to find where required test artifacts are downloaded. Done means transient download failures retry up to a configured limit with backoff and the affected test build succeeds.
