Artifact Repository

Nexus

The artifact repository delivered by Talend and based on Sonatype Nexus is a preconfigured application centralizing the management and usage of the Software Update, User libraries and snapshots and releases repositories:

  • Software Update is used to manage application updates (patches) distributed by Talend.
  • The User libraries repository is used to store all external libraries.
  • The snapshots and releases repositories are used as a catalog in which all artifacts to be deployed and executed are stored. These artifacts are designed by the user from the Studio or any other Java IDE. By default, the snapshots repository is used for development purposes and the releases repository is used for production. These repositories make artifacts available for deployment and or execution in an execution server.
