code for Version Purging

The wemblog code removes all newer versions except the base version, which is probably not what you want (keep the latest version only).

To get the code:

• search for VersionManagerImpl in CRXDE, this will give you a path like /libs/wcm/core/install/cq-wcm-core-5.6.24.jar
• create a package in package manager with that path, build it, download it, unzip it and extract the jar with "jar xf cq-wcm-core-5.6.24.jar"
• download a Java "disassembler" like http://jd.benow.ca/
• open the VersionManagerImpl.class file
• look at the "purgeVersions" method to see how its done

Hi,

If you are using AEM 6.0/6.1, here is another tool which could help you purging versions.

Can you please share the code for Version Purging  using  VersionManager (com.day.cq.wcm.api)

 

Give me some time. Will get back to you very soon. Trying to validate your code.

@Jitendra please find the code

public void clearOldVersions(Session session,String nodePath,Logger logger)
{
     VersionManager versionManager = null;
     VersionHistory versionHistory = null;
     VersionIterator versionItr = null;
     
     logger.debug("Starting clearOldVersions..");
    try {
        versionManager = session.getWorkspace().getVersionManager();
    } catch (UnsupportedRepositoryOperationException e)
    {
        logger.error("UnsupportedRepositoryOperationException",e);
        
    } catch (RepositoryException e) {
        logger.error("RepositoryException",e);
    }
     
    try {
        versionHistory = versionManager.getVersionHistory(nodePath);
    } catch (UnsupportedRepositoryOperationException e) {
        logger.error("UnsupportedRepositoryOperationException",e);
    } catch (RepositoryException e) {
        logger.error("RepositoryException",e);
    }
  
     // below return all versions in order of creation date
    
    try {
        versionItr = versionHistory.getAllVersions();
    } catch (RepositoryException e) {
        logger.error("RepositoryException",e);
    }

     //Since we know MaxVersion number then we need to iterate it accordingly. 

     //  get the names of the versions
     List<String> names = new LinkedList<String>();
    
     while (versionItr.hasNext()) {
        Version v = versionItr.nextVersion();
        try {
            if (!v.getName().equals("jcr:rootVersion")) {
               versionHistory.removeVersion(v.getName());
               logger.debug("Removing the version of "+nodePath);
            }
        } catch (AccessDeniedException e) {
            logger.error("AccessDeniedException",e);
        } catch (ReferentialIntegrityException e) {
            logger.error("ReferentialIntegrityException",e);
        } catch (UnsupportedRepositoryOperationException e) {
            logger.error("UnsupportedRepositoryOperationException",e);
        } catch (VersionException e) {
            logger.error("VersionException",e);
        } catch (RepositoryException e) {
            logger.error("RepositoryException",e);
        }
     }
     
     logger.debug("clearOldVersions....completed");
}

I didn't notice at first glance, But we are doing purging here. How does your code throws an exception which is more like "Not able to create version on a particular page."

Are you sure this exception is related to purging?.

Do you mind sharing your Version Purging code with me?.

@ Jitendera ,Its already versionable.please check the screen shot

 

 

Have you enable this node to make versionable?. Just verify whether it has a property (mix:versionable ) for version. If not, please add and then try it.

Ideally, this property should be at template level so that you don't need to add manually at individual pages.
