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

Commencez par com.google.gwt.eclipse.core.wizards.NewModuleWizardPage.moduleContainerChanged et l’appel défaillant à JavaPackageCompletionProcessor.setPackageFragmentRoot, puis reproduisez le flux de l’assistant de modules sur Eclipse 4.7. Comparez l’utilisation de l’Eclipse JDT API par le plugin avec la signature de méthode disponible. C’est terminé lorsque la création d’un module GWT s’achève sans le NoSuchMethodError.
