This might be useful github.com/timmacp/AppEngineGwt/tree/main
Its based on github.com/tbroyer/gwt-maven-archetypes
& Google Cloud Platform samples for App Engine with Java 11+
github.com/GoogleCloudPlatform/java-docs-samples/tree/main/appengine-java11/appengine-simple-jetty-main which shows how to have a separate jar module which run the WAR using the java command.
As in the GWT archetype it uses Jetty Maven Plugin for the development server & it covers Eclipse debugging,
appengine-maven-plugin is only for appengine:deploy

Hi Thomas,Aha!! You are correct, thank you - I have added it to my POM and now the breakpoints are getting triggered :-)Is there a way of limiting this configuration to a specific run configuration, or sometning? The way I have it set up I think the flags are passed every time?<plugin>

Unless you want to invest time and effort in getting eclipse plugins up and running, I would suggest using your browser's development tools (Ctrl+Shift+I in Chrome/Edge) to debug the client side. Thanks to source maps it will show your JAVA source code when debugging.To debug the server side, you need to start your server with "-Xdebug -Xrunjdwp:server=y,transport=dt_socket,address=8000,suspend=n" and create a debug configuration to connect to port 8000 in Eclipse.Good luckRalphOn Mon, Jun 24, 2024 at 11:19 AM 'Daniel Webb' via GWT Users <google-we...@googlegroups.com> wrote:Hi,Is it possible to debug GWT projects - setting breakpoints and stepping through code? This would be server and/or client debugging.We've just had our internal GWT based app updated and it now uses maven to run (clean install appengine:run). The eclipse plugin based debugging technique that I used to use no longer seems to work.Thanks for any advice, I really like GWT but I'm lost as to how it all works!Daniel--
