To make Artifactory servers globally available to project runner configurations, they must be defined in Administration | Integrations | Artifactory.
Select Create new Artifactory server configuration and fill in the URL of the Artifactory server.
Deployer credentials can be set at the global level for all builds, but they can also be overridden and set at a project build level.
Specifying a username and password for the resolver repository is optional. It is only used when querying Artifactory's REST API for a list of configured repositories and then only if the target instance does not allow anonymous access.
