Cannot instantiate interface

Question

When I tried to run my project(no build errors)there was an exception:

 Exception in thread "main" java.lang.IllegalArgumentException: Cannot instantiate interface org.springframework.context.ApplicationListener : org.springframework.boot.autoconfigure.BackgroundPreinitializer

I tried to resolve it, I updated my spring and jdk versions thinking it might be the reason but they all resulted in the same above exception.

Please see https://docs.spring.io/spring-native/docs/current/reference/htmlsingle/. It says

Spring Native 0.10.2 only supports Spring Boot 2.5.3, so change the version if necessary.

If you are running an older version of spring boot than 2.5.3, please try to upgrade and see if that helps.

See https://mvnrepository.com/artifact/org.springframework.boot/spring-boot-starter-parent for a list of available versions of spring boot.
