DEX660 - deploy POMs
The special profile deploy-to-exchange-v3 defined in the settings file and referenced in the BOM file is designed to enable publishing of parent POMs and BOMs as outlined in https://help.salesforce.com/s/articleView?id=001116554&type=1. Given the BOM and parent POM are already configured as outlined in the help document, all that’s required to run these commands from from the parent-pom or bom directory.
