GWT SuperDevMode. Code server compilaction doesn't see classes from dependent project

Question

I've just migrated my GWT application to version 2.7 and I would like to start using the SuperDevMode. Accodring to this video: http://jeff-davis.blogspot.fr/2012/07/setting-up-gwt-25s-superdevmode.html I've configured the CodeServer but whey I run it I am getting following errors in the logs:

The cern.edms.ui.shared.* packages come from external project added to GWT project by maven dependency.

Do you have any idea why they are not available when the code server is compiling the application?

Thank you for your help!

“I've just migrated my GWT application to version 2.7 and I would like to start using the SuperDevMode.” SuperDevMode is "on" by default when using DevMode in GWT 2.7; so you don't have to do anything, just run DevMode like you did before. — Thomas Broyer, Oct 21 '15 at 17:42
Thank you for pointing that. Please see also the answer added by me. — kpater87, Oct 30 '15 at 15:57

The cern.edms.ui.shared.* packages come from external project added to GWT project by maven dependency.

Does that dependency contain the sources for those classes? If not, is there another jar (like a -sources classifier) that might have them?

Without the sources on the classpath (or source path), the GWT compiler can't compile the app.

Yes, it contains. In fact I have two eclipse projects (let's call them A and B). Project B is GWT project and has dependency on Project A defined in the pom file. – kpater87 Oct 21 '15 at 14:25
I added the project A to the CodeServer run configuration classpath (like the gwt-codeserver jar), but it also doesn't help. – kpater87 Oct 21 '15 at 14:27
Dependency isn't enough, the jar needs to contain sources, or you need to reference the project itself (and not use maven to handle that dependency, your IDE should do this automatically if all projects are open in it). If the error is still "no source found", then either your .gwt.xml files are messed up (i.e. does it compile normally?), or your project setup is still not right. – Colin Alworth Oct 21 '15 at 15:41

The problem was that I didn't have all my source folders in the classpath. I was trying to add only whole projects, intead of the source folders of these projects.

Source folders were added automatically (after importing dependent projects) to the classpath when I've started running the application as 'Web Application (Super Dev Mode)' instead of creating java application for Code Server.
