Make sure that the Artifactory repository is already installed and launched. For more information, see https://jfrog.com/artifactory/.
If you are using an enterprise version of the Artifactory, unzip the Artifact-Repository-Artifactory archive file in a dedicated folder, and run the artifactory-init-VA.B.C.D.E.jar to initialize the Artifactory repository with repositories and users created and permissions set for the Talend Administration Center.
If you are using an open source version of the Artifactory, you need to create manually the users and repositories as for the Nexus repository. For more information, see Configuring Nexus.
