Yes, you look like you're lost :-)I'm afraid you can't develop in any given technology without learning the "basics" (between quotes, because it can mean a lot of things; learning curves are steep these days, and tending to become each year steeper than the preceding) : what is the classpath, a classloader, a JAR, a WAR, how to build a (simple) JAR (using the command-line, or some build tool), how to build a (simple) WAR. GWT adds a lot of things to those "basics", particularly when your build tool is as opinionated (and broken-by-design) as Maven.I'm a bottom-up learner, first learning how things work (from documentation, not experimentation) before doing something with them, rather than a top-down learner, first doing things (possibly copy/pasting snippets here and there "until it works") then trying to understand how and why it all worked. That makes me a terrible teacher for top-down learners, who are better served with heavy full-stack frameworks and full scaffolding (ultimately leading to a huge amount of third-party code to do a simple hello world, if you ask me). Please note that I'm not judging "top-down learners", everybody is different and learns differently; I'm only acknowledging I'm generally unable to help them. I'm not sure what kind of learner you are, just letting you know that if you're a top-down one, then I'm probably not the right "teacher", and my gwt-maven-archetypes haven't been tailored for you (I am expecting average knowledge of Maven and GWT).
First of all, thank you for being responsive. As a learner I try to combine both approaches. I.e., when I recently required the funcionality of my snapshots being automatically stored in the hand-crafted remote maven repository and further have them as maven dependencies in other projects, I first tried to comprehend maven by learning pom reference, gwt-maven-plugin wiki and other resources, and then successfully applied the knowledge to introduce this feature. But of cause it gave me only the superficial understanding of the subject. And therefore I can understand some things erroneously.
With your help I can see now clearer how servlet path is being resolved for containers on different stages and it finally makes sense. But I still struggle to have the tests from single-module project created by webAppCreater running the same way in the multi-module one. To focus on this problem I once again started a new project named myartifact, and left all packages by default (everything is withing com.example.project). But there're still some unresolved dependencies on sandbox-shared.
