//--- 
        TopComponent activeC = TopComponent.getRegistry().getActivated();
        FileObject dataLookup = activeC.getLookup().lookup(FileObject.class);
        if (dataLookup != null) {
            Project pro = FileOwnerQuery.getOwner(dataLookup);
            String path = pro.getProjectDirectory().getPath();
        }
