CBS Buld Failure

Hi,

I have created a Web Dynpro DC and it locally built perfectly. But whenever I'm trying to buld it through Developement Component Build service, it giving the following error:

/userOut/Development Component (com.sap.ide.eclipse.component.provider.listener.DevConfListener) [Thread[ModalContext,5,main]] ERROR: Build failed for <Applicatuion Name> in variant "default": null

Can anyone please help me to sort out this problem.
