Not able to create GWT module

I am using Oxygen. I created a GWT Project. Now when i try to create a Module by using File -> Other -> GWT Classes -> Module, it fails and throws this exception:

java.lang.NoSuchMethodError: org.eclipse.jdt.internal.ui.refactoring.contentassist.JavaPackageCompletionProcessor.setPackageFragmentRoot(Lorg/eclipse/jdt/core/IPackageFragmentRoot;)V

Comience con com.google.gwt.eclipse.core.wizards.NewModuleWizardPage.moduleContainerChanged y la llamada fallida a JavaPackageCompletionProcessor.setPackageFragmentRoot; después, reproduzca el flujo del asistente de módulos en Eclipse 4.7. Compare el uso que hace el plugin de la Eclipse JDT API con la firma de método disponible. Se considera completado cuando la creación de un módulo GWT finaliza sin el NoSuchMethodError.
