如何使用java添加一个nodeRef作为另一个节点的新版本？

RepositoryService repositoryService = new RepositoryService();
repositoryService.setEndpoint("http://your-alfresco-server/alfresco/api");
repositoryService.setAuthentication("username", "password");

NodeService nodeService = repositoryService.getNodeService();
NodeRef existingNodeRef = new NodeRef("workspace://SpacesStore/existing-node-id");

VersionService versionService = repositoryService.getVersionService();
NodeRef newVersionNodeRef = versionService.createVersion(existingNodeRef);

nodeService.setProperty(newVersionNodeRef, ContentModel.PROP_NAME, "New Version");
nodeService.setProperty(newVersionNodeRef, ContentModel.PROP_DESCRIPTION, "This is a new version of the node.");

nodeService.save();
