Hi, I try without success to remove some version from document with groovy :-( To refresh group cache I add & remove a member in a user group but I don't want my group be poluted by this operation. I want to launch this groovy script but unfortunaly this one crash with gArch.removeVersions("EndVersionToDel", "StartVersionToDel", context) I use http://maven.xwiki.org/site/docs/xwiki-javadoc-4.1.x/com/xpn/xwiki/doc/XWik… but I obtain this error: Caused by: javax.script.ScriptException: javax.script.ScriptException: groovy.lang.MissingMethodException: No signature of method: com.xpn.xwiki.doc.XWikiDocumentArchive.removeVersions() is applicable for argument types: (java.lang.String, java.lang.String, javax.script.SimpleScriptContext) values: [EndVersionToDel, StartVersionToDel, javax.script.SimpleScriptContext@4ee56e53] Possible solutions: removeVersions(org.suigeneris.jrcs.rcs.Version, org.suigeneris.jrcs.rcs.Version, com.xpn.xwiki.XWikiContext) If someone can help me? NB: groovy is complicated for me (and I don't understand what is context and how to get it) Thxs Pascal B {{groovy}} // My group to refresh def MyGroup = xwiki.getDocument('XWiki.GF_PiloteP3') // My temp user udoc = xwiki.getDocument('XWiki.xwikilecteur') // Add this temp user gObj = MyGroup.newObject('XWiki.XWikiGroups') gObj.set('member',udoc.fullName) MyGroup.save() // Store version to delete def StartVersionToDel = MyGroup.getVersion() print(MyGroup.getVersion() + "' \n") // Remove this temp user MyGroup.removeObject(gObj) MyGroup.save() // Store new version to delete def EndVersionToDel = MyGroup.getVersion() print(MyGroup.getVersion() + " \n") // get document Archive def gArch = MyGroup.getDocumentArchive() //try to remove 2 previous version archive gArch.removeVersions("EndVersionToDel", "StartVersionToDel", context) print(MyGroup.getVersion()+ " \n context: " + context + " \n") {{/groovy}}
