Widgetset Compilation Failed.

Hey everyone, I am having real hard time trying to get a widget set compiled.

I can not get my ant script to properly build. Also, I have eclipse, but I have not been able to find a way to get old vaadin project imported into eclipse.

Lastly, I noticed that even outside a vaadin project, I still have a compile widget set button. If I select a widgetset, it attempts to compile. but fails with:

Widgetset compilation failed

java.lang.NullPointerException
	at com.vaadin.integration.eclipse.handlers.CompileWidgetsetHandler$1.run(CompileWidgetsetHandler.java:98)
	at org.eclipse.core.internal.jobs.Worker.run(Worker.java:54)

Anyone have any ideas?

I'm trying to build vaadin-colorpicker-1.1.0.jar.

Thanks!
-Rob

I diagnosed the problem a bit further.

I was able to use project properties / project facets to make my application a web dynamic project. That enabled widget set compilation.

I now get this error. Any Ideas?

I'm going to try re-downloading the GWT SDK.

robert piskule: I'm going to try re-downloading the GWT SDK.

Indeed, this sounds like the wrong version (or two different versions) of a JAR (GWT or another related library) being on the compilation classpath.
