Vaadin 7.7.0 widgetset issue in Eclipse on Windows

Since installing Vaadin plugin for Eclipse version 3.0.0 I’ve been getting widgetset comple failures:
Exception in thread “main” java.io.IOException: Could not create directory for the widgetset: C:\Users\Peter%20Jacobs\workspace\ebms.core.ui\target\generated-resources\gwt

It just so happens I’m using the default workspace location, which has a space in my user name. This was not an issue in earlier plugin releases.

Seems like a regression bug. I created a
ticket
for this. Thanks for sharing.
