ClassNotFoundException: org.springframework.aot.ContextBootstrapInitializer
Hi folks,
I built my spring boot native images on macOs and Linux, but I executed the native images, then I got the following error both:
Exception in thread "main" java.lang.IllegalStateException: java.lang.ClassNotFoundException: org.springframework.aot.ContextBootstrapInitializer. This exception was synthesized during native image building from a call to java.lang.Class.forName(String) with constant arguments.

It is probably related to the fact Spring Native is only searching the main class in directories not JAR, see this related comment. This limitation will be remove in Spring Boot 3.
On Spring Native side, you should be able to make it work by configuring explicitly the main class at Spring AOT plugin level, see https://docs.spring.io/spring-native/docs/current/reference/htmlsingle/#aot-build-setup-configuration related documentation. You can search No application class detected, skipping context bootstrap in the logs to see if the application class is found or not.
