How to copy a node WITH THE FULL VERSION HISTORY with java ?

AlfrescoZZZ — Fri, 02 Jul 2021 15:22:30 GMT
The title alone explains the problem, I need to copy a node on Alfresco, but simultaneously copying all its version history. Here is the code I have prepared for this goal, but it doesn't seem to work.
Any help is welcome ...
	public static NodeRef copyWithHistory(NodeRef actionedUponNodeRef, NodeRef destinationParent, 
			boolean deepCopy, boolean overwrite,
			ServiceRegistry serviceRegistry) {
		
		CopyService copyService = serviceRegistry.getCopyService();
		CheckOutCheckInService checkOutCheckInService = serviceRegistry.getCheckOutCheckInService();
		NodeService nodeService = serviceRegistry.getNodeService();
		VersionService versionService = serviceRegistry.getVersionService();
		ContentService contentService = serviceRegistry.getContentService();
		DictionaryService dictionaryService = serviceRegistry.getDictionaryService();

		// Since we are overwriting we need to figure out whether the destination node exists
        NodeRef copyNodeRef = null;
        
        if (overwrite == true)
        {
            // Try and find copies of the actioned upon node reference.
            // Include the parent folder because that's where the copy will be if this action
            // had done the first copy.
            PagingResults<CopyInfo> copies = copyService.getCopies(
                    actionedUponNodeRef,
                    destinationParent,
                    new PagingRequest(1000));
            for (CopyInfo copyInfo : copies.getPage())
            {
                NodeRef copy = copyInfo.getNodeRef();
                // We know that it is in the destination parent, but avoid working copies
                if (checkOutCheckInService.isWorkingCopy(copy))
                {
                    continue;
                }
                if (copyNodeRef == null)
                {
                    copyNodeRef = copy;
                }
                else
                {
                    throw new AlfrescoRuntimeException("Cannot override hte file already exists");
                }

        }

        {
            // Overwrite the state of the destination node ref with the actioned upon node state
            copyService.copy(actionedUponNodeRef, copyNodeRef);
        }
        else
        {
            ChildAssociationRef originalAssoc = nodeService.getPrimaryParent(actionedUponNodeRef);
            // Create a new copy of the node

Hi @4535992
Could you be a little more specific when you say it doesn't work? Does it fall over with an error, does it fail at a particular point in your code, are there any error message in the logs, etc?
Including information like this wil help others to help you.
Cheers,
