Hello, I'm trying to import a xar published to my local maven repository. I've setup the local repository in xwiki.properties: extension.repositories=maven-local:maven:file:///c:/Users/jbousque/.m2/repository My extension exists in this repository: C:\Users\jbousque\.m2\repository\org\xwiki\contrib\mailarchive\xwiki-contrib-mailarchive-ui\0.2\xwiki-contrib-mailarchive-ui-0.2.xar When trying to import extension with id "org.xwiki.contrib.mailarchive:xwiki-contrib-mailarchive-ui", I get the following error: Failed to import extension: class org.xwiki.extension.ResolveException: No versions available for id [org.xwiki.contrib.mailarchive:xwiki-contrib-mailarchive-ui] at org.xwiki.extension.repository.aether.internal.AetherExtensionRepository.resolveVersions(AetherExtensionRepository.java:252) at org.xwiki.extension.repository.xwiki.internal.DefaultRepositoryManager.getVersions(DefaultRepositoryManager.java:409) at org.xwiki.extension.repository.xwiki.internal.DefaultRepositoryManager.importExtension(DefaultRepositoryManager.java:430) at org.xwiki.extension.repository.xwiki.internal.RepositoryScriptService.importExtension(RepositoryScriptService.java:100) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(Unknown Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke(Unknown Source) at java.lang.reflect.Method.invoke(Unknown Source) [...] And from the logs (with debug activated for "org.xwiki.extension.repository" and "org.sonatype.aether") : [http://.../ExtensionCode/ImportExtension?parent=Extension.WebHome&template=ExtensionCode.ExtensionTemplate&importExtension=true&extensionId=org.xwiki.contrib.mailarchive%3Axwiki-contrib-mailarchive-ui&repositoryId=maven-local] DEBUG .DefaultPlexusComponentManager - Using connector FileRepositoryConnector with priority 1 for file:///c:/Users/jbousque/.m2/repository [http://.../ExtensionCode/ImportExtension?parent=Extension.WebHome&template=ExtensionCode.ExtensionTemplate&importExtension=true&extensionId=org.xwiki.contrib.mailarchive%3Axwiki-contrib-mailarchive-ui&repositoryId=maven-local] DEBUG .DefaultPlexusComponentManager - Writing resolution tracking file C:\Users\jbousque\AppData\Local\Temp\jetty-0.0.0.0-8097-xwiki-_xwiki-any-_2086184271349922709\xwiki-temp\aether-repository\org\xwiki\contrib\mailarchive\xwiki-contrib-mailarchive-ui\resolver-status.properties Content of resolver-status.properties is: maven-metadata-maven-local.xml.error= maven-metadata-maven-local.xml.lastUpdated=1351257375255 Can't find what's wrong here ...
