Fixed version (ground truth):

    IPath itemDesPath=null;
    if (property != null) {
      itemPath=PropertyHelper.getItemPath(property);
    }
 else {
      String currentProjectName=ResourceManager.getRootProjectName();
      itemPath=new Path(currentProjectName).append(record.getFullPath().removeFirstSegments(1));
    }
    itemDesPath=ResourcesPlugin.getWorkspace().getRoot().getFile(itemPath).getLocation();
    IPath propDesPath=itemDesPath.removeFileExtension().addFileExtension(FactoriesUtil.PROPERTIES_EXTENSION);
    toImportMap.put(record.getFilePath(),itemDesPath);
    if (property == null) {
      return toImportMap;
    }
    toImportMap.put(record.getPropertyPath(),propDesPath);
    EResourceConstant typedConstant=EResourceConstant.getTypedConstant(property.getItem());
    if (typedConstant != null && typedConstant == EResourceConstant.MDM_CONNECTIONS) {
      ConnectionItem item=(ConnectionItem)property.getItem();
      Connection connection=item.getConnection();
      List<TdXmlSchema> tdXmlDocumentList=ConnectionHelper.getTdXmlDocument(connection);
      for (      TdXmlSchema schema : tdXmlDocumentList) {
        IPath srcPath=record.getFilePath().removeLastSegments(1).append(schema.getXsdFilePath());
        if (!srcPath.toFile().exists()) {
