Installable with the Extension Manager


Provide tools to tweak extension that are usually either not polished enough or too dangerous to be part of the standard Extension Manager.

Current feature:


Contains tools related to installed extensions.

  • Move to wikis: sometime you install an extension on root namespace ("On farm" in EM UI) by mistake, this tool allow "moving" a root extension to each existing wikis
  • Clean: get rid of extensions that have been uninstalled and kept in the local repository
  • Repair XAR extension: allow repair FS metadata of an installed XAR extension
  • Set dependency marker: allow changing the dependency marker of an extension (generally so that it's taken into account or not by the upgrade job)


Is a class from which you can create configuration to automate installation of extension using the EM. Please note that recent version of XWiki as a built-in feature for the same purpose.


This page provides a table listing every extension marked as installed on the server, with at least one namespace in which the extension has been manually installed.

Prerequisites & Installation Instructions

We recommend using the Extension Manager to install this extension (Make sure that the text "Installable with the Extension Manager" is displayed at the top right location on this page to know if this extension can be installed with the Extension Manager). Note that installing Extensions when being offline is currently not supported and you'd need to use some complex manual method.

You can also use the following manual method, which is useful if this extension cannot be installed with the Extension Manager or if you're using an old version of XWiki that doesn't have the Extension Manager:

  1. Log in the wiki with a user having Administration rights
  2. Go to the Administration page and select the Import category
  3. Follow the on-screen instructions to upload the downloaded XAR
  4. Click on the uploaded XAR and follow the instructions
  5. You'll also need to install all dependent Extensions that are not already installed in your wiki
