## Known Issues

Intermittent build failures while downloading dependencies from maven central.
Root issue seems to be SNAT configs in Azure, which closes long running TCP connections
only on one side: https://docs.microsoft.com/en-us/azure/load-balancer/troubleshoot-outbound-connection#idletimeout
The default timeout is 4 minutes.

Workaround as described in https://github.com/actions/virtual-environments/issues/1499 and
https://issues.apache.org/jira/browse/WAGON-545 is applied:

`-Dmaven.wagon.httpconnectionManager.ttlSeconds=180 -Dmaven.wagon.http.retryHandler.count=3`
