Because we're putting the jetty dependencies into the p2 repository, the changes to this pom affect all the platform definitions we use. So now that this is updated to use 12.0.6 and pull in the jetty ee9 dependencies (which are the 12.X.X), 2023-12/2023-09/2023-03 can't build because it's unable to find the 10.0.18 versions of the jetty-related dependencies.

And this way each platform-definition we have could just reference the same version that is shipped by that Eclipse release?



For the class **WebsocketServer.java**, we need **org.eclipse.jetty.websocket.servlet (Jetty 10.0.18)** or **org.eclipse.jetty.ee9.websocket.servlet (Jetty 12.0.6)**. These are not present in https://download.eclipse.org/releases/2024-03/202403131000/plugins/.
