So, firstly mvn --version provided the JDK 17.02, but the JDK version can be set with "export JAVA_HOME= "
I installed JDK 11 and used the POM.xml configuration you suggested. I also exported the JAVA_HOME in the shell session to make sure that JDK 11 is used (with export JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk-11.0.13.jdk/Contents/Home/). I got only the error : ERROR: Type 'openllet help' for usage. No more information in the output. I repeated with JDK 13 getting the same error. it would be great to port fuseki to JDK 17 as JDK 11 is pretty old.
