@Colin, thanks for getting back to me on this. I couldn't reply right away because my wife was getting cataract surgery; it's not that this wasn't important.
> If you mean a particular plugin that you use with GWT... I'm using the Eclipse GWT 4.0.0 plugin you guys recently completed (using the updated build, to fix the "support Eclipse 2024-03" issue; thanks for that). I think in your lingo I therefore mean the dev mode app server. I might look into that myself to get jetty-12 implemented, but for now I've abandoned jumping to jakarta as "a bridge too far" and am trying to solve my issues another way (likely by grumbling, rolling up my sleeves, and refactoring the mess the way it should have been done to start with, and the way I would have demanded had I worked here when it was first bungled). > If using maven... [I'm not]... If not, please give us more detail about what you are using (or intend to use). After further investigation, much of my issues around this seem to be that the. appropriate java command to run the web app (or Jetty itself) is not being assembled correctly by either Eclipse, the GWT plugin, or both. There are various options that are needed and are not properly set. That said, even if I do/can get that working, I don't think that's the right approach. As you're going to deprecate the embedded Jetty server, I should do whatever is needed there to run my own external server(s). That's what's unclear to me. There are ancient references to it in the documentation at gwt.project.org, but I'm unclear on what is really needed. Do I need to set up and run a code server with my own Jetty or Tomcat local installation? If so, how is that set up? Or do I need to run my own app server (again, either Jetty or Tomcat). The web app setup is obvious (I think... or are there special runtime parameters to direct it to the proper code server port?). Forgive my ignorance on this, but if this is the path forward for GWT in general, I'd really like to see some clear documentation on how to set this up or at least what it is going to look like (in general, no specifics, obviously it should involve thinking and work on my part). Last note: I am assuming the code server will be easier to get working with Java 17 modules because it will (in my case) have less jar dependencies, as it only needs them for shared and client code. That said... I might need to run both externally to get it all sorted out. Again, my own thinking on this isn't that clear because I'm not in the weeds enough on what the plugin is really doing and how things work under the hood. To give a shorter, more direct answer: I want to develop code in Eclipse in Java 17, and be able to run the code server and web app any way possible, so that GWT code compiles/recompiles as needed, and the web app can be accessed in the browser, and I can do iterative test-code-test-code development on a daily basis. > GWT doesn't have a BuildException class This was my bad. When I got the conflict I assumed it was something in gwt-dev.jar related to GWT, but upon further investigation (unpacking the jar), I see that the conflict is caused because the ant BuildException.class file is embedded in the get-dev.jar (and possibly because the package/path is com/google/gwt/thirdparty/apache/ant/BuildException.class rather than Ant's org/apache/tools/ant/BuildException.class. A recurring problem in upgrading to Java 17 comes from class name/version exceptions that are now verboten. My current solution of getting Ant out of this project will have to do (as it's better architecture anyway, and should have been done by my predecessors on day 1, i.e., don't bundle custom Java ant tasks with the application code).
