Yo can use below code to merge two xml file at specified xpath root is the xml to which you need to merge another xml. insertDoc is the document which you need to add/you can even pass node. And xpath is path of the xml where you need to add the second xml.

public void generateDocument(Document root, Document insertDoc, String xpath) {

        if (null != root) {

            Node element = insertDoc.getDocumentElement();
            Node dest = root.importNode(element, true);

            try {
                Node node = getNode(root, xpath);
                node.insertBefore(dest, null);
            } catch (ParserConfigurationException ex) {
                Logger.getLogger(ProcessXML.class.getName()).log(Level.SEVERE,
                        null, ex);
            } catch (SAXException ex) {
                Logger.getLogger(ProcessXML.class.getName()).log(Level.SEVERE,
                        null, ex);
            } catch (IOException ex) {
                Logger.getLogger(ProcessXML.class.getName()).log(Level.SEVERE,
                        null, ex);
            } catch (XPathExpressionException ex) {
                Logger.getLogger(ProcessXML.class.getName()).log(Level.SEVERE,
                        null, ex);
            }

        }

And you can use exec-maven-plugin to execute java code refer usage of plugin here
