I installed xwiki inside tomcat9 and with postgresql 14.
I configured the company proxy in the last line of /opt/apache-tomcat-9.0.64/bin/catalina.sh.
JAVA_OPTS="$JAVA_OPTS -Dappserver.home=$CATALINA_HOME -Dappserver.base=$CATALINA_HOME -Dhttp.proxyHost=proxy.example.com -Dhttp.proxyPort=3128 -Dhttps.proxyHost=proxy.example.com -Dhttps.proxyPort=3128 $XWIKI_OPTS"
But there are no extensions available in the Initialization Wizard of xwiki.
And there is no way to add them later on.
I can import Packages manually in the admin page but it does not do anything.
I can import this xwiki-platform-distribution-flavor-xip-13.10.8.xip but nothing happens.
Unzipping it in /opt/apache-tomcat-9.0.64/webapps/xwiki/WEB-INF/extensions/repository also does not help...
Also how do I reinitialize xwiki to go back to the installation wizard at the beginning?
I unzipped the standard flavour extension in the wrong directory.
It has to be in the environment.permanent_directory which is given in the TOMCAT_HOME/webapps/xwiki/WEB-INF/xwiki.properties and the default is /var/lib/xwiki/data when you just comment it out.
So I unzipped it in /var/lib/xwiki/data/extensions/repository/ and then restarted tomcat9.
Then the installation wizard automatically came back without doing any reset.
And then I could install all extensions from inside the web interface.
