Spring boot error UnsupportedClassVersionError with Intellij

Question

I have an application in Spring Boot with Tomcat. I needed to make update in my repository maven, and after this, started with this error:

Exception in thread "main" java.lang.IllegalArgumentException: Cannot instantiate interface org.springframework.context.ApplicationContextInitializer : org.springframework.boot.devtools.restart.RestartScopeInitializer at org.springframework.boot.SpringApplication.createSpringFactoriesInstances(SpringApplication.java:423) at org.springframework.boot.SpringApplication.getSpringFactoriesInstances(SpringApplication.java:402) at org.springframework.boot.SpringApplication.getSpringFactoriesInstances(SpringApplication.java:393) at org.springframework.boot.SpringApplication.initialize(SpringApplication.java:260) at org.springframework.boot.SpringApplication.(SpringApplication.java:236) at org.springframework.boot.SpringApplication.run(SpringApplication.java:1162) at org.springframework.boot.SpringApplication.run(SpringApplication.java:1151) at br.coopercarga.com.br.SistemacolaborativoApplication.main(SistemaApplication.java:23)

My SistemaApplication.java

import br.xxxxx.com.br.TokenFilter.TokenFilter;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.web.servlet.FilterRegistrationBean;
import org.springframework.context.annotation.Bean;

@SpringBootApplication
public class SistemaApplication {

    @Bean
    public FilterRegistrationBean getFilterJWT() {
        FilterRegistrationBean frb = new FilterRegistrationBean();
        frb.setFilter(new TokenFilter());
        frb.addUrlPatterns("/#/*");

        return frb;
    }


    public static void main(String[] args) {
        SpringApplication.run(SistemaApplication.class, args);
    }
}

I've already tried updating Java, and reconfiguring my project, but without success, I did several searches, but no solution worked, so any help I'd appreciate.

Answer 1

Your parent is Springboot 2.x but then you added Springboot 3 dependencies, that require Java 17 https://spring.io/blog/2022/05/24/preparing-for-spring-boot-3-0
