Hi, I am very sure maven-artifact-transfer is not the issue.
The real issue is MavenSession.ProjectBuildingRequest.RemoteRepositories, needed by maven-artifact-transfer, has snapshot resolution disable For my case, I am using maven setting's mirror to route all pom's repositories to my internal maven repository. This also means I have only one remoteRepository with this content from my debugger id: xxx url: http://my.internal.repo/public layout: default snapshots: [enabled => false, update => daily] releases: [enabled => true, update => daily] What could have caused this? I am seeing this issue on all maven 3.1+ Thanks -Dan
