Widget Set recompilation problem

General
1

I have been working on a project for several months now - building it (successfully) using Eclipse and Vaadin.
Yesterday I did an update on Vaadin (to version 6.7.8) and tried to recompile the project widgets. I think it succeeded, but
I’m not sure. The output from the console window is shown below…

I tried doing an update of Eclipse itself, and it downloaded quite a number of files. But I still get this output. Can someone tell me
what I’ve screwed up?

Where should I be looking to see exactly what widgets should be recompiled?

Thanks very much,

nbc

Hmm looks more like an eclipse problem to me. Have you tried stepping back to the version of Vaadin that did work for you?
To see if your widgets will compile then?
It also can be that the add-ons themselfs you are using are to old and they need to be updated to a later version of vaadin.
It all depens on the version of vaadin you where using at the time your project worked still.
(you can change the vaadin version back to an older version by right clicking your Eclipse project then select: properties->Vaadin and then select the version that did work for you)

Well, just a guess: It looks like you either are missing the javax.validation-Classes completely (is there an JEE-6-Impl in the classpath? I mean not only somehow referenced by the eclipse-project but really accessible through Ant?) or at least missing the source for those files (the latter might be true if the errors are coming from the GWT-compiler).

4

I did try the earlier version of vaadin - with the same failure result… I think I’m missing something in the class path, as was suggested. Not sure why or how that happened, since I have compiled this project (and the widgets) many times. I will see if I can find the missing libraries…

thanks,

As addition to my previous post: It might even be, that you have edited your widgets so that they now depend on javax.validation.*. The GWT-Compiler only needs classes in sourcecode that are somehow referenced by the code in *.client-Package - even an indirect reference would do it!

6

From which version did you upgrade? Probably one that used an older version of GWT, the current one requires the validation JARs (although your widgetset would probably work despite the error messages).

If you have the latest Vaadin plug-in for Eclipse version, try to first downgrade Vaadin version to an old one (pre-6.7), apply the changes and then re-upgrade it to 6.7.8 using Project Properties → Vaadin. That should trigger the loading of the required GWT version and its dependencies, and the validation JARs will be used in widgetset compilation.

7

I ended up just re-installing Eclipse (the same version as before) and then installing the Vaadin plugin along with the latest jar file. When I re-created my projects, they all seemed to work. Not sure exactly where I went wrong, but I’m back in operation now. Thanks…

Hi,

I don’t know if this could fix your problem but it fixed mine.

I added the validation-api-1.0.0-GA.jar and I added the validation-api-1.0.0-GA-sources.jar to my classpath and it worked.
