Vaadin Widgetset compilation error

I’ve tried to recompile Vaadin Widgetset because I updated my version, so I need to recompile the Widgetset. But I have a problem while it was compiling and I can’t resolve it because I don’t find information about that.

Next I copy the console output:

With Maven I don’t have problems compiling, but I’m not using maven now.

Thanks you!

Hi,
there is something wrong with class com.google.gwt.editor.client.SimpleBeanEditorDriver which seems to be referenced in one of the GWT module descriptors:

 [WARN]
 Detected warnings related to 'com.google.gwt.editor.client.SimpleBeanEditorDriver'. 
Are validation-api-.jar and validation-api--sources.jar on the classpath?
[WARN]
 Unknown type 'com.google.gwt.editor.client.SimpleBeanEditorDriver' specified in deferred binding rule 

Have you checked that the two validation jars are on the classpath for the GWT compiler? BTW, it’s a bit strange that there is an extra hyphen in the name of the jars (validation-api–sources). Could this somehow be related with the problem?

Thanks for the answer. I have this .jar into my Java Class Path. I use Eclipse.

Really I don’t know about the error. I have researched for weeks.

Thanks!
