Adobe CM Pipeline - Build Error

Hi All,

I am getting the below issue - 

For the same commit id in Adobe Git, I got the deployment failed the first time but succeed the second time. 

Build #1 - 
22:27:04,861 [main] [INFO] Downloading from digital-mvn-build-dependencies: https://pkgs.dev.azure.com/cantire/_packaging/digital-mvn-build-dependencies/maven/v1/io/netty/netty-bom/4.2.15.Final/netty-bom-4.2.15.Final.pom

I understand this is because the artifact could not be downloaded hence maven didn’t resolve the import BOM. Even if maven central was rate limiting temporarily.
Why would this be an intermittent issue? 

My sequence of builds is - SUCCESS - FAIL - SUCCESS - FAIL - FAIL over past 24 hours.

Thanks in advance,

NK
