During the development of a new Java recipe I faced the following exception.
Error while visiting lib/persistence/src/main/java/com/mycompany/persistence/entity/StudyLog.java: java.lang.IllegalStateException: Unable to construct Java21Parser.

}The error occurred because I wasn't providing a the full classpath. As soon as updated the line .javaParser(JavaParser.fromJavaVersion().classpath("jakarta.jakartaee-api", "hibernate-core")) and add the dependency to the Maven rewrite plugin.
My ask here is to improve the Java21Parser message to quick pin point the missing classpath.
