Yes, works! > "mvn gwt:devmode" and "mvn gwt:codeserver" should work without too much > configuration (configure warDir/launcherDir, possibly projects/modules) > Actually, it gives an error (see below): Could not find goal 'devmode' in plugin org.codehaus.mojo:gwt-maven-plugin:2.8.0 among available goals... I believe I have to extend the minimal top-level pom.xml, but how? And I'd like to leave the pom.xml in the sub folders as is, because they are working for their own...

If the app used the library jar from the repository and not from its own target directory, there would be no need to "mvn package" the app and this takes most of the time... > Wouldn't it be better for developing if the original library code was used >> instead?

But as soon as I enable it for the app project, the error reappears. It's hard to figure it out when even the experts in this group have no idea. But I see that this is an essential point, so I have documented the error as detailed as possible again (see below). I hope there will be a solution...
