Hi,
The develop documentation refers to 1.13 which we’re currently working on and has not officially been released. You can experiment with the jar from https://artifacts.oicr.on.ca/artifactory/webapp/#/artifacts/browse/tree/General/collab-release/io/dockstore/dockstore-client/1.13.0-rc.0/dockstore-client-1.13.0-rc.0-shaded.jar but this isn’t officially supported.
