We'd like to introduce a naming convention as we have a large number of both internal and external repositories and thus we'd like to make it obvious what's what. At the time these repositories were added, nobody expected things to grow this much.
I was wondering if it would be possible to rename the repositories? I know I can create new ones and copy/move the artifacts there, but that looks like a bigger effort than I'd like. Is there a reasonable way to do this?
No and yes. You shouldn't, but you can. I guess you can imagine why you shouldn't, and for all those reasons the name is not editable in the UI.
You can edit the names in the settings.xml (in the UI under Admin->Advanced, by REST) or as a file, bootsraping Artifactory with it). All three ways are described here.
Note that you do it on your own risk.
I am with JFrog, the company behind Bintray and [artifactory], see my profile for details and links.
