[xwiki-users] Repository Extension: How to import an extension from a maven repository

Hi, I like to use the Extension Repository Application in XWiki 4.2 to host our homemade XWiki extensions. For this purpose I configured our Apache archiva instance in xwiki.properties as extension repository: extension.repositories=ourmaven:maven:http://ourmaven:8081/archiva/repository/main I am struggling now with importing the extensions in the http://localhost:8080/xwiki/bin/view/ExtensionCode/ImportExtension page. What is the syntax of an extension id for maven artifacts? Our extensions are normal XAR Files. Do we have to enhance the XAR Files with additional information? Richard
