如何解决错误java。郎。异常为XPATH? 专家的依赖性加入

我得到以下错误

 java.lang.RuntimeException:  Trying XBeans path engine... Trying XQRL... Trying XDK... Trying delegated path engine... FAILED on data(//v:shape[contains(@id,'PowerPlusWaterMarkObject')]/v:textpath/@string)

同时执行下列代码

private String getWaterMark(XWPFDocument document) {
   try {
        XWPFHeader defaultHeader = document.getHeaderFooterPolicy().getDefaultHeader();
        final String xpathFilter = "data(//v:shape[contains(@id,'PowerPlusWaterMarkObject')]/v:textpath/@string)";
        XmlObject[] xmlobjects = defaultHeader._getHdrFtr().selectPath(xpathFilter);
        return xmlobjects[0].toString();
   } catch (Exception ex) {
       logger.error("Error while getting Watermark content from document: ", ex);
   }
}

我已经加入了以下相关性在 pom.xml 文件。
