I try to use Code Name One with Apache Netbeans 22 and JDK 21 and also tried with JDK 22.
I followed the guide "Create your project using Codename One initializr" from this yrl https://www.codenameone.com/getting-started.html.
I downloaded the a kotlin template project from Codename One initializr and try to build it but I get error.
Source root doesn't exist: /****/tools/MyApp/myapp/common/src/main/java
Using experimental Kotlin incremental compilation
and the stack trace

To see the full stack trace of the errors, re-run Maven with the -e switch.
Re-run Maven using the -X switch to enable full debug logging.
It's first time I use it and don't know where to start from.
Codename One required either JDK 11 or JDK 8 to build. Newer JDKs or anything in between these isn't supported due to significant changes in the javac tool and backward compatibility.
