Fixed version (ground truth):

  }
 else   if (FactoriesUtil.REP.equalsIgnoreCase(file.getFileExtension())) {
    findModelElement=RepResourceFileHelper.getInstance().findReport(file);
    if (findModelElement == null) {
      return findModelElement;
    }
    List<Resource> modifiedResources=new ArrayList<Resource>();

        EList<ModelElement> client=dependency.getClient();
