-
The default connection mode for the Java CLI client is now
webSocket.
You can specify http to continue to use the former default (for example because you are running Jenkins in a servlet container other than the recommended builtin Jetty, or because you are running an unusual reverse proxy which does not support WebSocket).
You can also continue to specify ssh to use SSH transport (for example because you prefer to authenticate with a private key rather than an API token), or use a native SSH client.
