After downloading apache-log4j-2.24.3-bin.zip in my Debian 12, Iunzipped 
it into ~/opt and following the instructions in 
~/opt/apache-log4j-2.3.2-src/log4j-api/BUILDING.txt, first I ran the 
'mvn apache-rat:check' command, no errors there. However, when running 
'clirr:check' I get some errors :


*~/opt/apache-log4j-2.3.2-src/log4j-api$ mvn clirr:check
