Software development teams usually collaborate and work off of one or multiple repository and they need to utilize the artifact built from these repos into the image. Relative path for the artifact remains same, as everyone builds from the same repo, where each developer clones the repo is usually developer’s choice.
Team shortcuts allows team to create a variable which represents this path from root and every artifact that you built from that source repo is referenced from the team shortcut. So when the team member is using the image, they have to configure this one team shortcut and all paths relative to shortcut gets resolved automatically.
For example : In your image you want to refer to an artifact built at : "/Users/user1/Documents/Code/organization/repo-name/package-name/target/artifact.kab" and "/Users/user1/Documents/Code/organization/repo-name/package-name2/target/artifact2.kab"
Here you would create a team shortcut for the repo, which is referencing repo location as repo-location and you will map your image to use artifact from : "{{repo-location}}/package-name/target/artifact.kab" and "{{repo-location}}/package-name2/target/artifact2.kab"
So next time your team members are using the same image, they will have to just update the team shortcut to point to their repo location and image will refer to the artifact at defined location without need to reconfigure each artifact separately.
