No source code is available for type com.sencha.gxt; did you forget to inherit a required module?

Question

I am developing ear application, with gwt web module and ejb module. maven builds succesfully. I inherited gxt module. In hosted mode my application doesn't render. In gwt dev mode I see following errors:

[ERROR] Line 62: No source code is available for type com.sencha.gxt.widget.core.client.Window; did you forget to inherit a required module? ERROR] Line 71: No source code is available for type com.sencha.gxt.widget.core.client.container.VerticalLayoutContainer; did you forget to inherit a required module? [ERROR] Line 73: No source code is available for type com.sencha.gxt.widget.core.client.form.FieldSet; did you forget to inherit a required module? .. ..

00:00:15.285 [ERROR] Hint: Check the inheritance chain from your module; it may not be inheriting a required module or a module may not be adding its source path entries properly

here is my gwt.xml

<module rename-to='xxx'>
 <!-- Inherit the core Web Toolkit stuff.                        -->
 <inherits name='com.google.gwt.user.User'/>

 <inherits name="com.google.gwt.resources.Resources" />

  <inherits name="com.sencha.gxt.ui.GXT" />

  <entry-point class='com.example.XX'/>



   <source path='client'/>
   <source path='shared'/>

 </module>

and here is my my pom.xml for gwt web app

please help me. there is no compilation error during maven build

Have tried to clean the project? maven -> update project? create a new run configuration? — Fedy2
If it can be compiled to JS but can't be run in dev mode, something is wrong with your dev mode setup. Can you share the full log? Are you sure that the gxt jar (and others) are on the dev mode run config's classpath? — Colin Alworth

In your [projectname].GWT.xml you also have to add a reference to GXT

<inherits name='com.sencha.gxt.ui.GXT'/>

No source code is available for type com.sencha.gxt; did you forget to inherit a required module?
