I'm afraid you're not providing enough information for us to help. First, I'm assuming you read https://tbroyer.github.io/gwt-maven-plugin/migrating.html, as well as https://tbroyer.github.io/gwt-maven-plugin/index.html and https://tbroyer.github.io/gwt-maven-plugin/usage.html. If you haven't already, I'd suggest studying the structure of a project generated from the gwt-maven-archetypes: https://github.com/tbroyer/gwt-maven-archetypes/ or the e2e project used in tests (https://github.com/tbroyer/gwt-maven-plugin/tree/main/src/it/e2e)
How's your code organized in your project? Is the client code in a separate project from the server code? Or both in the same project? How did you configure the net.ltgt.gwt.maven:gwt-maven-plugin? How was the CodeHaus Mojo plugin configured? You're mentioning src/main/java in the structure of "Third-Party JAR (T1)", does it mean it's a project in the same Maven reactor build? Or is it really a third-party JAR and it actually doesn't have a src/main/java? The best way to troubleshoot is to run with debug logs (mvn -X) and look for two lines starting with "Classpath:" and "Arguments:" respectively. You can also compare their content vs. the content of the two lines starting with "Execute command" and "With CLASSPATH" emitted by the CodeHaus Mojo plugin in the debug logs.
