Error while running the GWT developer mode

Question

While starting my application in the GWT dev mode from Intellij. I got the following error:-

 ERROR: Failed to create an instance of 'com.vaadin.client.ApplicationConnection' via deferred binding 
java.lang.RuntimeException: Deferred binding failed for 'com.vaadin.client.metadata.ConnectorBundleLoader' (did you forget to inherit a required module?)

I understands from the error that i missed to inherit any module. But in which module does this "com.vaadin.client.ApplicationConnection" comes as it's class of vaadin itself. I'm using vaadin 7.4.6 version <inherits name="com.vaadin.DefaultWidgetSet" /> is already inherited.

Answer 1

I'm able to solve this issue and sharing it here, it might be helpful for others.

• Removed all old compiled widget sets from the target
• Recompile the the whole full project again

And then I found, it starts working fine.
