I am trying to import on-premise confluence instance to xwiki and always I get the following error in the middle of import regardless of how small the import is:
'void org.xwiki.rendering.internal.parser.wikimodel.WikiModelParserUtils.parseInline(org.xwiki.rendering.parser.StreamParser, java.lang.String, org.xwiki.rendering.listener.Listener, boolean)'
class java.lang.NoSuchMethodError: 'void org.xwiki.rendering.internal.parser.wikimodel.WikiModelParserUtils.parseInline(org.xwiki.rendering.parser.StreamParser, java.lang.String, org.xwiki.rendering.listener.Listener, boolean)'

I am not a Java person and I really don't know what it really means. Can someone please help me with this?
The XWiki API used by XWiki Extension Confluence XML 9.14.4 has been changed and is now breaking the Confluence XML import, beginning with XWiki 13.10.4 and 14.2.
XWiki Jira issue XRENDERING-6 is causing the NoSuchMethodError: https://jira.xwiki.org/browse/XRENDERING-6
XWiki Extension Confluence XML Jira issue CONFLUENCE-103 has been created to fix the issue: https://jira.xwiki.org/browse/CONFLUENCE-103
What can you do? Either wait until CONFLUENCE-103 has been fixed in XWiki Extension Confluence XML 9.14.4+. Or use a XWiki release older than 13.10.4, eg. 13.10.3. For me Confluence XML import worked as expected using XWiki 13.10.3
