NoSuchMethodError on Spring Boot Security - spring

Question

I'm following this tutorial : https://www.baeldung.com/spring-boot-security-autoconfiguration to add Simple Auth. to my Spring Boot Project. When i try to run my application i always get this error :
Factory method 'springSecurityFilterChain' threw exception; nested exception is java.lang.NoSuchMethodError: org.springframework.util.Assert.isTrue(ZLjava/util/function/Supplier;)V
IDK why im getting this or is this related something about Version problem. Do you guys have any idea about this ?

You can relate your question with this answer
pom.xml
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-security</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-test</artifactId>
<scope>test</scope>
<exclusions>
<exclusion>
<groupId>org.junit.vintage</groupId>
<artifactId>junit-vintage-engine</artifactId>
</exclusion>

security configuration class
#Configuration
#EnableWebSecurity
public class Config extends WebSecurityConfigurerAdapter{
#Override
protected void configure(AuthenticationManagerBuilder auth) throws Exception {
auth.inMemoryAuthentication()
.withUser("username")
.password("password")
.roles("ADMIN","USER");
}
#Override
protected void configure(HttpSecurity http) throws Exception {
http.cors().and()
.csrf().disable()
.authorizeRequests()
.antMatchers("/greetings").hasRole("ADMIN")
.and()
.httpBasic()
.and()
.sessionManagement().sessionCreationPolicy(SessionCreationPolicy.STATELESS);
}
}
A simple restController
#GetMapping("/greetings")
public String greetings(){
return "Hello World!";
}
this is the basic security using memory authentication. you can relate your pom.xml and configuration.class, In most cases spring-boot, resolves the versions by default.
