Hi All,

I am trying to build an already existing maven project using mvn clean install -P autoInstallPackage

I am getting the below error:-

I am able to connect to URL https://repo.adobe.com/nexus/content/groups/public/com/day/jcr/vault/content-package-maven-plugin/1.... using my browser and my settings.xml file for m2 has https based URL. https://repo.adobe.com/nexus/content/groups/public

Could you please let me know how to resolve this issue ?
