Hi!

After reading some guides on SuperDeathMode ( by Broyer, Kurka and Gwt Documentation ) and consulting the FAQ I could not find the answer.

How does one stop / restart the CodeServer using the goal gwt:run-coderserver ?

Ultimativaly I am trying to feed the CodeServer Gwt-Modules ,that were created after the CodeServer was started.

Best regards, Oliver

Ctrl+C on your console, or killing the process.
(to be honest, I don't use gwt:run or gwt;run-codeserver, I launch them from within Eclipse)

Ctrl+C'ing does not work if you launched the goal as Maven build command in Eclipse. Also using Eclipse Run configurations violates maven policy of "central configuration".
I really like the run-codeserver goal, and if we are the only ones in need of this functionality I would patch this myself . Any hints and tips are most welcome though ;)
Generally I see two ways of dealing with this:
1. implicitly : Have the SuperDevModeMojo kill the CoderServer if the port is used
2. explicitly : Introduce "stop" and "restart" flags

Any thoughts?

Can't you stop the "build" from the Maven console view? Or would it only kill Maven and let the SuperDevMode running in the background "detached" from its parent process?
(I tried gwt:run-codeserver back in July when I added support for it and I don't recall having had problems with stopping it)

I'm unfortunately not doing much GWT dev at the moment (our "big" GWT project at work entered maintenance mode); so any suggestion is welcome.
 
Also using Eclipse Run configurations violates maven policy of "central configuration".

The main reasons I don't use gwt:run is because it's much easier to debug the code when launched from Eclipse. And as for gwt:run-codeserver, it doesn't work well with multi-module builds (just like gwt:run; see https://jira.codehaus.org/browse/MGWT-332)

Wow, this issue runs deeper than expected :)
Thanks for pointing me to the issue. I wasn't aware of this. We will probably resort to Eclipse Run Command as well in the near future.

I can only guess but I believe the solution in general would be to customize the maven lifecycle phases ( similiar?  ) and add "gwt" and "gwt-lib" as packaging types.

By the way, on Windows 7 + maven + eclipse stopping the "build" from console view behaves as you expected, it is "detached", the server keeps running in
the background

In the long run, that's exactly what I'd like to do (create new packaging types); I don't think it'd solve the issue though (it however doesn't mean it's that hard to solve either; I just didn't took the time to do it, given how much better launching from Eclipse is compared to gwt:run for attaching a Java debugger; SuperDevMode is different though)

I am experiencing this currently. Have posted a question here: http://stackoverflow.com/questions/24866301/maven-gwt-plugin-error-address-already-in-use-bind

Has nothing been done or is there no workaround? I can end the java process, it's no big deal but I would prefer not to.

:)

I found that killing the code server will leave you with large files eating up your temporary directory (see attachment) ..

It depends how you kill the process. When allowed to terminate gracefully (SIGINT or SIGTERM), then those temporary files should be cleaned up.
Eclipse for instance sends a SIGKILL so the JVM (and/or the application) cannot do any cleanup before exiting: https://bugs.eclipse.org/bugs/show_bug.cgi?id=38016
FWIW, IntelliJ IDEA gives you the choice: https://www.jetbrains.com/help/idea/2016.1/run-tool-window.html (exit vs. stop)
